Question

Based on the graph below, what is the solution to the equation f(x) = g(x)?

Answer 1

x = -4 and x = 2

x = -4 and x = 2.5

x = -5.1 and x = 2.1

x = -5.1 and x = 1.5

Answer 2

Can someone please explain how to do this?

Answer 3

Well, f(x) and g(x) represent y-values. So what the question is asking is for what x-values do f(x) and g(x) have the same y-value (or simply cross each other)

Answer 4

So they're asking where they intercept?

Answer 5

What is the x-value where they intercept, yes.

Answer 6

None of the answer choices seem reasonable to me though

Answer 7

f(x)=g(x) at x1 and x2

Answer 8

If I may use mathmath's drawing.

Answer 9

Nvm, not sure how, haha. Oh well, so look at this:

Answer 10

So, the circles represent where they cross. The x-values you're looking for are located on the horizontal axis (the x-axis). So where they intercept, you're looking straight down and seeing what x-value that is
