Question

The function f(x) =4x+3 represents the length of a rectangle. The function g(x)=2x-5 represents the width of the rectangle.Use (f•g)(4) to determine the area of a rectangle

Answer 1

Answer:

45 square units

Step-by-step explanation:

g(4)=2(4)-5=8-5=3

f(g)=f(3)=4(3)+3=12+3=15

area=length*width=3*15=45
