Answer:
The rate of change for the given function is 6.
Step-by-step explanation:
Given function is:
The interval on which we have to find the rate of change is:
1≤x≤2
Here
a = 1
b = 2
We have to find the values of function on both points
Putting 1 in place of input (x)
Putting x = 2
The rate of change is calculated by using the following formula
Hence,
The rate of change for the given function is 6.
Answer:
it will be -12 F
Step-by-step explanation:
IT is already -2 F so if you add -2 + -10= -12
An x-intercept is what x is equal to when y, or in this case q(x) is equal to 0. Lets set our equation up.
0=-2(x+3)^2 +8
-8=-2(x+3)^2
4=(x+3)^2
+-2=x+3
x=3+-2
x=1,x=5
