Question 5 Of 10 The Graph Shows The Function Fx 2x What Is The Value Of X When Fx 4 class=

Answer:

A. 2

Step-by-step explanation:

Our y-axis is equivalent to f(x), so we can use it to find the value of x when f(x) = 4. If we look at the graph, we can find that an f(x) value of 4 (or, a y-value of 4) has an x-value of 2.

We could also figure this out by making f(x) equal to 4 in the equation:

[tex]4=2^{x}[/tex]

2 times itself how many times is equal to 4? Well, 2 times 2 is equal to 4, so 2 times itself two times is equal to 4. x is equal to 2:

[tex]4=2^{2}[/tex]

Either way works. If you have any more questions, let me know! :)
