Question

PLEASE HELP ASAP
Select the correct answer from each drop down menu if f(x)=0.5x^2-2 and g(x)=8x^3+2 find the following function (f•g)(x)= (BLANK 8.5,7.5,4,0,40) x^5 - (BLANK 6,16,0,4,5) x^3+ (BLANK 1,0,2.5,5) x^2 - (BLANK 0,4,2,-4)

Answer 1

Answer:4x^5-16x^3+x^2-4

Step-by-step explanation:

f(x)= 0.5x^2-2

g(x)=8x^3+2

(f*g)(x)=(0.5x^2-2)(8x^3+2)

         =(0.5x^2*8x^3)+(0.5x^2*2)-(2*8x^3)-(2*2)

         =4x^5-16x^3+x^2-4
