Answer
The Math is below, and the graph is attached.
Work Step by Step
We plug in the given values of x into the equation to find:
A) $f(2) = .2 + .3(2) = .8$
B) $ f(5) = .2 + .3(5) = 1.7$
C) The graph is attached.
D) In order to estimate, first draw a vertical line at x=4. Then, estimate the value of f(x) at the intersection. This value is 1.4. After all:
$f(4) = .2 + 3(.4) = 1.4$
