If f(x) = 8 - 10x and g(x) = 5x + 4, what is the value of (f9)(-2)?
Replace x in each equation with -2:
f(x) = 8 -10(-2) = 8 +20 = 28
g(x) = 5(-2) + 4 = -10 + 4 = -6
Now multiply the two"
28 Β * -6 = -168
The answer is -168

Answer from: Quest
f(x) = - 2/3x + 5; f(5/2)
substitute 5/2 in for x:
f(5/2) = -2/3(5/2) + 5
simplify the right side:
f(5/2) = -5/3 + 5
f(5/2) = 10/3
answer:
f(5/2) = 10/3
i hope this you!
