If c(x) = 4x − 2 and d(x) = x² + 5x, what is (c.d)(x)?
snow_lady [41]

Answer:

4x^2+20x-2

Step-by-step explanation:

To find (c.g)(x) we basically use the function d(x) as your variable, x, and plug it into c(x). So we replace every x in c(x) with the function d(x), x^{2} +5x

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

c(g(x))4x^2+20x-2
