# If c(x) = 4x - 2 and d(x) = x^{2} + 5x, what is c(d(x))?

**Solution:**

A function that depends on any other function is called a composite function.

A composite function is created by composing one function within another function.

Given,

c(x) = 4x - 2

d(x) = x^{2} + 5x

We have to find c(d(x))

We know that

c(d(x)) = c(x^{2} + 5x)

Substituting the values

= 4(x^{2} + 5x) - 2

So we get

= 4x^{2} + 20x - 2

Therefore, c(d(x)) = 4x^{2} + 20x - 2.

## If c(x) = 4x - 2 and d(x) = x^{2} + 5x, what is c(d(x))?

**Summary:**

If c(x) = 4x - 2 and d(x) = x^{2} + 5x, then c(d(x)) 4x^{2} + 20x - 2.
