The graph shows the equation x = y2. Use the slider for a to move the vertical line on the graph. According to the vertical line test, is this equation a function? Why or why not?

Not a function, you would get a parabola open to the right. y = √x and y = -√x

Step-by-step explanation:

No. The vertical line touches the graph at more than one point at once.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
