If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
Add up all the numbers & divide by the number of numbers. That should give you the mean.
Answer:
D) Quadratic
Step-by-step explanation:
A function is graphed on a coordinate grid.
- As the domain values approach infinity, the range values approach infinity.
Domain: If
then
Range:
- As the domain values negative infinity, the range values approach infinity.
Domain: If
then
Range:
We need to choose correct option which follows given domain and range.
Only quadratic function will follow the rule because it has even degree polynomial.
Quadratic function:
Degree = 2 and leading coefficient is positive.
Domain: 
Range: 
Hence, D is correct option.
