A function is when every input has one output.
Easiest way is to do the "vertical line test" and "horizonal line test."
Basically you draw a vertical line and a horizontal line.
If either line passes through more than one point, then it is not a function.
The only one that passes them is B, the line.

Answer:
6x + y
Step-by-step explanation:
Answer:
x= 8 and x=-9
Step-by-step explanation:
The x intercepts are found when we set y = 0
0 = (x-8) (x+9)
Using the zero product property
x-8 =0 and x+9=0
x= 8 and x=-9
Answer:
300
Step-by-step explanation:
Evaluate 2 y^2 (y + x) where x = 1 and y = 5:
2 y^2 (y + x) = 2×5^2 (1 + 5)
Hint: | Evaluate 1 + 5.
1 + 5 = 6:
2×5^2×6
Hint: | Evaluate 5^2.
5^2 = 25:
2×25×6
Hint: | Multiply 2 and 25 together.
2×25 = 50:
50×6
Hint: | Multiply 50 and 6 together.
50×6 = 300:
