Can somebody please help me with these two questions?

Problem 3

This is not an exponential function. If you were to graph this out, you would see a parabola forming. Or at the very least, a parabolic-like curve forms. An exponential curve only increases or only decreases for the entire domain. However, in this case, we have an increasing portion, and then it decreases.

---------------------------------------------------------------------

Problem 4

This is an exponential function. Each time x increases by 1, y is multiplied by 4. The equation that models these points is y = 4^x. Note how the function is strictly increasing and there are no decreasing portions mixed in.

Which equation represents this situation?
Anika [276]

Answer:

I would say...

C.)x - 5 = 3 (x + 2)

Really really sorry if I'm wrong...

One thing I can say is that when it says 5 less than a #, that means the # is being subtracted from another #...
