Identify the graph of y= 2^x + 3

A

Step-by-step explanation:

This function involves exponential growth, so we can immediately discard the 3rd and 4th answer choices.  

Now if x = 0, e^x = 1.  Taking the +3 vertical offset into account, we get 4.  The first answer choice is the correct one; the y-intercept is at (0, 4).

what’s the question?

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
