Question

What is the graph of the function rule y=|4x|-3?

Answer 1

That will equal to y=4x-3 and the graph will look like a V mainly with the minimum on the point (0,-3)  hope this helps\ <span />

Answer 2

we have

$y=\left|4x\right|-3$

Using a graphing tool

see the attached figure

The vertex of the function is the point $(0,-3)$

The x-intercept of the function are the points  $(-0.75,0)$ and  $(0.75,0)$

the answer in the attached figure
