Solution Summary: The author explains how to calculate the value of (gf).
Consider the function f(x) = 3x-2 and the function g(x), which is represented by the table below
The function f(x)=0.5(2)xf(x)=0.5(2)x represents the growth in square centimeters of a fungus after x days.
Which of the following are TRUE? Select all that apply.
A
f(8)=1f(8)=1
B
f(8)=128f(8)=128
C
f(10)=512f(10)=512 represents the value of the function after 10 days.
D
f(64)f(64) represents the amount of fungi after 64 days.
E
f(85)f(85) represents the amount of days it takes for the fungi to reach 85 cm2cm2
Evaluate the function for f(x) = x + 3 and g(x) = x2 – 2.
(f + g)(-8)
(f + g)(-8) =
