Suppose $f'(x) = \sin(x^2)$ and $f(0) = 3$.

A. Use a graph of $f'(x)$ to decide which is larger:
A. $f(0)$
B. $f(0.7)$

Use a graph of $f'(x)$ to decide which is larger:
A. $f(2.5)$
B. $f(2.1)$

B. Estimate $f(b)$ for:
$b = 0$ : $f(b) \approx$
$b = 1$ : $f(b) \approx$
$b = 2$ : $f(b) \approx$
$b = 3$ : $f(b) \approx$
