5-142.

Given $f(t)=2+\int_0^tf^\prime(x)dx$, where $y = f ′(x)$ is shown on the graph in problem 5-141. Calculate the following values: Homework Help ✎

1. $f (1)$

This is 2 plus the area under the curve for 0 ≤ x ≤ 1.

2. $f ^\prime(1)$

Notice that the graph is of f '(x).

3. $f (-3)$

Refer to hint in part (a).

4. $f^\prime(-2)$

Refer to hint in part (b).

5. $f ^{\prime \prime}(2)$

f ''(x) represents the slope of f '(x) and you are looking at the f '(x) graph.
