Question

The graph of an absolute value function f(x) = axl includes the point (1. 8). Complete the following statements.

Answer 1

The graph of the function f(x) = a|x| is symetrical rwith espect tto he y-axis, therefore ,if the point (1, 8) is included ,then the point (-1, 8) must be included too.

The point (1, 8) indicates that f(x) = 8 when x = 1, then:

`\begin{gathered} 8=a\cdot|1| \\ 8=a\cdot1 \\ (8)/(1)=a \\ 8=a \end{gathered}`
