anonymous · Answer

b^(-1/2)=5. What is b?

yoloshroom · Answer

I see, so that's how you do it? i ws confusing myself then lol

anonymous · Answer

You plug in the given point into the parent function that is given to you.

anonymous · Answer

plug in (-1/2, 5) into f(x)=b^x.

anonymous · Answer

then solve for b to determine the exponential function.
