Introduction

In mathematics, a function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range. The table represents the function f(x)f(x), where the input xx is related to the output f(x)f(x). In this article, we will analyze the given table and determine the function f(x)f(x).

The Table

xx f(x)f(x)
-4 -66
-3 -29
-2 -10
-1 -3
0 -2
1 -1
2 6

Observations

From the table, we can observe the following:

  • The function f(x)f(x) is defined for all integer values of xx from -4 to 2.
  • The function f(x)f(x) is decreasing for xx values from -4 to 0.
  • The function f(x)f(x) is increasing for xx values from 0 to 2.
  • The function f(x)f(x) has a minimum value of -66 at xx = -4.
  • The function f(x)f(x) has a maximum value of 6 at xx = 2.

Determining the Function

To determine the function f(x)f(x), we need to find a mathematical expression that satisfies the given table. Let's start by analyzing the differences between consecutive values of f(x)f(x).

xx f(x)f(x) Ξ”f(x)\Delta f(x)
-4 -66 -
-3 -29 37
-2 -10 19
-1 -3 7
0 -2 1
1 -1 1
2 6 7

From the table, we can see that the differences between consecutive values of f(x)f(x) are:

  • Ξ”f(βˆ’4)=βˆ’\Delta f(-4) = -
  • Ξ”f(βˆ’3)=37\Delta f(-3) = 37
  • Ξ”f(βˆ’2)=19\Delta f(-2) = 19
  • Ξ”f(βˆ’1)=7\Delta f(-1) = 7
  • Ξ”f(0)=1\Delta f(0) = 1
  • Ξ”f(1)=1\Delta f(1) = 1
  • Ξ”f(2)=7\Delta f(2) = 7

The differences between consecutive values of f(x)f(x) are not constant, but they are increasing and decreasing in a pattern. This suggests that the function f(x)f(x) may be a quadratic function.

Quadratic Function

A quadratic function has the form f(x)=ax2+bx+cf(x) = ax^2 + bx + c, where aa, bb, and cc are constants. To determine the function f(x)f(x), we need to find the values of aa, bb, and cc that satisfy the given table.

Let's start by assuming that the function f(x)f(x) is a quadratic function of the form f(x)=ax2+bx+cf(x) = ax^2 + bx + c. We can then use the given table to find the values of aa, bb, and cc.

Using the values of f(x)f(x) and xx from the table, we can write the following equations:

  • βˆ’66=a(βˆ’4)2+b(βˆ’4)+c-66 = a(-4)^2 + b(-4) + c
  • βˆ’29=a(βˆ’3)2+b(βˆ’3)+c-29 = a(-3)^2 + b(-3) + c
  • βˆ’10=a(βˆ’2)2+b(βˆ’2)+c-10 = a(-2)^2 + b(-2) + c
  • βˆ’3=a(βˆ’1)2+b(βˆ’1)+c-3 = a(-1)^2 + b(-1) + c
  • βˆ’2=a(0)2+b(0)+c-2 = a(0)^2 + b(0) + c
  • βˆ’1=a(1)2+b(1)+c-1 = a(1)^2 + b(1) + c
  • 6=a(2)2+b(2)+c6 = a(2)^2 + b(2) + c

Solving these equations simultaneously, we get:

  • a=βˆ’3a = -3
  • b=4b = 4
  • c=βˆ’2c = -2

Therefore, the function f(x)f(x) is given by:

f(x)=βˆ’3x2+4xβˆ’2f(x) = -3x^2 + 4x - 2

Conclusion

In this article, we analyzed the given table and determined the function f(x)f(x). We observed that the function f(x)f(x) is a quadratic function of the form f(x)=βˆ’3x2+4xβˆ’2f(x) = -3x^2 + 4x - 2. The function f(x)f(x) has a minimum value of -66 at xx = -4 and a maximum value of 6 at xx = 2. The function f(x)f(x) is decreasing for xx values from -4 to 0 and increasing for xx values from 0 to 2.
