Question

Find the avg rate of change of the function f(x)=x^2+5x from x1= 1 to x2=3

Answer 1

rate of change is another way of saying slope. So use the 2 x-values given to determine the y values (f(x)). Then find the slope between those 2 points

Answer 2

1/3?

Answer 3

can you help me with one more CHmE

Answer 4

you need to redo this problem. \[\text{slope}=\frac{y_2-y_1}{x_2-x_1}\]

Answer 5

what is the other y value?

Answer 6

you find both by plugging in the 2 x-values given into the equation

Answer 7

1 and 3

Answer 8

\[y_1=(1)^2+5(1)\]\[y_2=(3)^2+5(3)\]

Answer 9

y1=7 y2= 21
