Question

which of the following statements is true about f(X)=-2(3)^X
it has a y-intercept at(0,-2)
it has a y-intercept at (0,3)
its graph is a line
its graph is a parabola

Answer 1

Hint:
Exponential functions of the form : \(f(x)=a (b^x)\) has a y-intercept equal to a, since \(b^0=1\).

Answer 2

it has four answer choices do you see them

Answer 3

Yes, I see all four answer choices.
I hope you are able to pick one of them based on the hint I gave. :)

Answer 4

its parobala right?

Answer 5

Try to construct a table of values and plot the function (unless you have a TI-83).
First determine the type of function you are working with, then solve the problem, ok?
