Question

I could really use some help on this!

"the table shows values for functions f(x) and g(x) (table below)

What is the solution to f(x)=g(x)

Select each correct answer"

1. -6
2. -5
3. -4
4. -3
5. -2
6. -1
7. 0

Answer 1

3. -4

4. -3

Explanation:

Given the functions of f(x) and g(x) the solution to f(x) = g(x) is when the value of 'x' produces the same answer for both equations. Looking at the table, when x = -4, both f(x) and g(x) = 4 and when x = -3, both f(x) and g(x) = 8. For example:

f(x) = 4x + 20

g(x) =
`2^(x+6)`

When x = -3:

f(x) = 4(-3) + 20 = 8

g(x) =
`2^(-3+6)=2^(3)=8`
