Question

Is the graph of y=x^2 a function

Answer 1

it is a function

Step-by-step explanation:

y = x²

For the graph to be a function, it must have only one input and output. In other words, for every value of x, we will only have one value of y.

We will plot the graph to determine if it is a function:

From the graph:

when x = 2, y = 4

when x = -2, y = 4

Since there are only one y value for the x value, it is a function
