True or False
2: Given the graph of the exponential function f(x)=b^x for which the base, b, is greater than 1. The function f is a one-to-one function.
True or False ... do you understand what a one-to-one function is?
3:f(x)=log3x is the inverse of g(x)=x^3.
True or False
the inverse of x^3 is x^(1/3)
the inverse of log(3x) is b^(3x) , depending on the base, b,of the logarithm.
4:Given the graph of the exponential function f(x)=b^x for with the base, b, is greater than 1. The range of f is y>=0
True or False
for b > 0 , f(x) = b^x can never equal 0
