Answer:
x = -2
And, x = 7 ÷ 2
Step-by-step explanation:
Given that
y = 2x^2
y = 3x + 14
Now equate these two above equations
2x^2 = 3x + 14
2x^2 - 3x - 14
2x^2 -7x + 4x - 14
x(2x - 7) + 2(2x - 7)
(x + 2) (2x - 7)
So it can be x = -2
And, x = 7 ÷ 2
Just substitute the x for each of the values and do the work
Answer:
The vertical line test is a way for you to see if a graph represents a function. It allows you to identify if any x values have more than one y value.
A graph would be a function if every input (x) has exactly one output (y). A graph would not be a function if an input (x) has more than one output (y).
Step-by-step explanation:
In a function, every input within the domain of the function must have exactly one output. If the graph has an input that has more than one output, then it is not a function. The vertical line test is what allows you to see if a graph is a function or not.
