Step-by-step explanation:
Answer: Not a function
<u>Step-by-step explanation:</u>
The graph fails the vertical line test. In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.
Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.
For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).
X^2 - x - 90 =0
This equation is in standard form ax^2+ bx + c
The sum of the solutions is -b/a (a and b are the coefficients from the equation above, not the solutions to the equation)
The answer is 1/1 = 1
