Your friend says two different translations of the graph of the parent linear function can result in the graph of f(x)=x-2.is your friend correct explain why

The given linear function is f(x) = x-2

The parent function of this linear equation is y=x

Your friend's way of explaining this function is not quite correct.

If the transformation in the function is of the form , then the graphs moves up or down vertically in the y- axis direction depending upon the value of c.

If c>0, then the graph moves up.

If c<0, the graph moves down.

Comparing the given equation with , we notice, c = -2 which is less than 0.

Hence the graph moves down by 2 units.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

47 - 90 = 43

43 - 180 = x

x = 137
