Question

Two functions are shown in the table below:


Function 1 2 3 4 5 6
f(x) = −x2 + 4x + 12
g(x) = x + 8


Complete the table on your own paper, then select the value that is a solution to f(x) = g(x).
x = 3
x = 4
x = 5
x = 6

Answer 1

:I

Answer 2

To fill out the table, plug each x value into each function, starting with x = 1.

For f(x) = −x^2 + 4x + 12, f(1) = -1^2 + 4(1) + 12 = ?
For g(x) = x + 8, g(1) = 1 + 8 =?

Repeat for all the x values

The solution is the x value that makes both functions equal
