Work Step by Step
Q – 88
(a) F(x)=15(40- x) if 065
(b) When x=30
F(x)=15(40- x)
Now substitute the value of x to the above equation
F(30)=15(40- 30)
=150
When x=50
F(x)=0
Now substitute the value of x to the above equation
F(50)=0
When x=75
F(x)=15(x-65)
Now substitute the value of x to the above equation
F(75)=15(75-65)
= 150
(c ) The fine for violating the speed limits.
