Answer:
Step-by-step explanation:
The
average rate of change
of f(x) over an interval between 2 points (a ,f(a)) and (b ,f(b)) is the slope of the
secant line
connecting the 2 points.
To calculate the average rate of change between the 2 points use.

This means that the average of all the slopes of lines tangent to the graph of f(x) between (4 ,0) and (9 ,35) is 7.
There's lots of even functions, but two that come to mind are the absolute value function, IxI, and x^2. These are even because they are reflected over the y axis. Another way to find this is that (-x)^2 is equal to x^2 and so is I-xI, the algebraic method. Good luck!
Answer:
.78
Step-by-step explanation:
3.90/5 = .78
Answer:
B
Step-by-step explanation:
PLS GIVE ME BRAINLIEST
(7^2)x = 1
49x = 1
x = 1/49
Part B
7^0 = 1
so we have
1x = 1
x = 1
