Answer:
- 3x² + x + 5
Step-by-step explanation:
Given
(4x + 5) + (- 3x² - 3x) ← remove parenthesis
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + (4x - 3x) + 5
= - 3x² + x + 5
As per definition
In. a function every domain has an unique range of it
Here
- f(4)=6
- f(10)=-2
- f(13)=7
- d(15)=8
- f(10)=11
f(10) has two corresponding values hence it's not a function
Answer:

Step-by-step explanation:
First, look at the graph and pick out two points that we can use for the slope equation. I see (0,2) and (-2,5) as two possibilities. Now, we just plug them into the slope equation. Remember that the slope equation is

(the '2' and '1' are subscripts, <u>not</u> exponents)
Let's call our first point (0,2) x1 and y1. (-2,5) can be the second point.
If we plug this into the equation:

Now we just simplify and get

Our slope is
.
I hope this helps!
