Question

Please help :/ Find f^-1(x) if f(x)=5x-2/4
f^-1(x)= ?

Answer 1

If f(x) = −4x − 2, find f(−3)

f(-3) = -4*(-3) - 2 = 12 - 2 = 10


If h(x) = 2x + 1, find the value of x if h(x) = 11.

2x + 1 = 11
2x = 10
x = 5


If f(x) = x + 4, find f(3).

f(3) = 3 + 4 = 7


If g(x) = 2(x − 4), find the value of x if g(x) = 20.

2(x − 4) = 20
x - 4 = 10
x = 14

hope this helps u
