Question

If f(x) = x2 and g(x) = 3x - 1 find [ gºf(x)​

Answer 1

gºf(x)​ =
`3x^2 -1`

Explanation:

Given

f(x) = x2

g(x) = 3x - 1

To find

gºf(x)​

To find gºf(x)​ we will use value of f(x) =
`x^2` in place of in g(x)

lets do that

g(x) = 3x - 1

gºf(x)​ = 3(f(x)) -1

gºf(x)​ =
`3x^2 -1`

Thus, value of gºf(x)​ is
`3x^2 -1`.
