An easy way to determine the slope of a roof is to set one end of a 12-inch level on the roof surface and hold it level. Then ta
ke a tape measure or ruler and measure from the other end of the level down to the roof surface. This will give you the slope of the roof.
The slope of the roof shown here is measured with a 12-inch level and a ruler.

<u>ANSWER</u>
Only the equation is a function
<u>EXPLANATION</u>
is graphed above with its inverse
.
We perform the vertical line test for both the equation and its inverse.
The equation passed the vertical line hence it is a function.
However, failed the vertical line test, hence it is not a function.
