Answer:
(C) -11
Step-by-step explanation:
The given functions are;

Plug in x=3.
This implies that; 
and

Plug in x=-1
This implies that; 

6a + 3b - 4a - 5b
Gather the a's and b's together: 6a - 4a + 3b - 5b
Add up the a's : 2a + 3b - 5b
Add up the b's : 2a + -2b
There you are: 2a - 2b
Answer:
The average rate of change

At t = 1

at t=3
Step-by-step explanation:
<u><em>Step(I)</em></u>:-
The given function h(t) = 3+70t - 16t²

The
70 - 32 t = 0
⇒ 70 = 32 t
⇒ 
<em>Step(ii</em>):-
The average rate of change in h(t) between t = 1 second and t = 3 second

At t = 1

At t = 3
Answer:
The value of given expression is 1.
Step-by-step explanation:
Consider the given expression is

When e=12 and
.
Substitute e=12 and
in the given expression.

On simplification we get


Therefore, the value of given expression is 1.
I know that this is an old question, but I'll add my input for future reference. The graph shown above is B) This is a function (as it passes the vertical line test), but it is NOT a one-to-one, as it fails the horizontal line test.
