The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].
Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.
Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.
Then the integral is approximately
so 78.0 is the correct answer.

Answer:
Step-by-step explanation:
We have:
And we want to solve for y when x is -9.
So, substitute -9 for x and evaluate:
Hence, when x is -9, y is -13.
You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
The equation is
y=-2(12)+15
the y intercept is b, therefore y, 15, is b
y =MX+b is slope intercept form
y=-2(12)+15
