select all the true statements about exponential functions:

Question

-b can be any real number

-The standard form is: a + b^x +k

--The y intercept is: a+k

-f(x)=b^x is the parent function

-The horizontal asymptote is: y=k

Answer 1

think of this in terms of the standard exponential function f(x) = e^x

but the base e could have been any real positive number

the standard form is f(x) = a(b)^x + k

where f(x) = b^x is the standard function.

shift it up by k, and the horizontal asymptote is y=k

the last two are most true, the others need to be fixed up a little to be true
