Question

if c(x)=4x-2 and d(x)=x^2+5x what is c(d(-1))

Answer 1

Step-by-step explanation:

d(x)=x^2+5x

d(1)=1-5=-4

c(d(-1))=-18

Answer 2

Answer:

Solution:

c(x)=4x-2

c(x)=4(x)-2

c(x)=4(x)-2

c(d(x))=4(d(x))-2 (replace every x with d(x) )

c(d(x))=4(x^2+5x)-2 (replace the d(x) on the right side with x^2+5x)

c(d(x))=4*x^2+4*5x-2

c(d(x))=4x^2+20x-2
