Question

Help I don't know where to start
Look at the picture then we are trying to Evaluate each of the following
f(5)=?
f(8)=?

Answer 1

This is one of the ones with limits form 0 to x. Remember when we looked at that before? It means you add up the area under the graph.

Answer 2

ok so f(5)=5 and f(8)=3

Answer 3

AREA

Answer 4

right isn't that what I did

Answer 5

wait f(5)=11

Answer 6

they say f(x) is the integral of g(x)

that means the area under the curve of g(x)

Answer 7

f(8)=4

Answer 8

between x=0 and x=5, g(x) is a trapezoid and you can find the area of a trapezoid
(or you can count the squares)
