x=0
x=10
x=24
Step-by-step explanation:
f(x) = -.05x^2 + x +6
The initial value is 6 ( Let x=0 and f(0) = 6)
f(x) = -.05( x^2 -20 x -120)
I plotted the equation and maximum is at x=10 and the zero is at x=25
Answer:
C) 160
Step-by-step explanation:
Set up a proportion:
=
Cross multiply and solve for x:
15x = 3600
x = 240
