Answer:
slope intercept form is y=x+1
In the region 0-2, the first derivative has a zero at x=1, and the second derivative (slope of the first derivative line) is positive. This means f(x) will have a minimum at x=1.
Likewise, in the region 4-6, the second derivative is negative and the first derivative is zero at x=5, indicating a maximum there.
These observations narrow the selection to choices A or C. The derivative curve is continuous at x=2 and x=4, so there will not be any discontinuities in f(x)--eliminating selection C.
The best choice is
A.

Answer:-150t-110
Step-by-step explanation:
-10(5t+5)-10(10t+6)
-50t - 50 - 100t - 60
=
-150t-110
