Find the inverse for each of the following functions.

a) f(x)=6x+10
f−1(y)=

b) g(x)=15x2−8, with domain x≥0
g−1(y)=

c) h(x)=6x+8
h−1(y)=

1 answer

f = 6x+10
f-10 = 6x
(f-10)/6 = x = f^-1

g = 15x^2-8
g+8 = 15x^2
(g+8)/15 = x^2
√((g+8)/15) = x = g^-1

I'm sure you can handle the last one, right?
