What do "a" and b" represent in exponential functions: y=a*b^x?
a. "a" is the y-intercept, "b" is growth rate (if b>1 it decays, 0<b<1 it grows)
b. "a" is the y-intercept, "b" is growth rate (if b>1 it grows, 0<b<1 it decays)
c. "a" is the growth rate (if a>1 it decays, 0<a<1 it grows), "b" is the y-intercept
d. "a" is the growth rate (if a>1 it grows, 0<a<1 it decays), "b" is the y-intercept
b.
