Question

What would the Outputs be when the Inputs are -2,-1,0,1,and 2 if it says "Absolute value of x and then subtract 7?"

Answer 1

The phrase "absolute value of x and then subtract 7" can be expressed as:

`f(x)=|x|-7`

With this expression we can calculate the outputs for the given inputs.

`\begin{gathered} f(-2)=|-2|-7=2-7=-5 \\ f(-1)=|-1|-7=1-7=-6 \\ f(0)=|0|-7=-7 \\ f(1)=|1|-7=-6 \\ f(2)=|2|-7=-5 \end{gathered}`

The function outputs -5 when the input is -2, then -6 when the input is -1, -7 when the input is 0, -6 when the input is 1 and -5 when the input is 2.
