g(x) dx
Step 1
If g(x) is positive, then the integral
g(x) dx corresponds to the area beneath g(x) and above the x-axis
over the interval [a, b].
On [0, 4], the function g(x) is above the x-axis and is therefore positive. Thus,
g(x) dx equals the area of
the triangle created by the function, the x-axis, and the y-axis.
This triangle is a right triangle with a side length of
4 along the x-axis and a side length of 8
8 along the y-axis. (Give the numeric values.)
