<span>y ≥ 0 is the range of this absolute value expression because the absolute value means x can never go below 0 and range means the y value, which here is equivalent to |x|</span>
3^2 + 4^2 = 5^2
65/5=13
3x13 =39
4 x 13= 42
Let f(x)=0, you'll get x=3 and x=-5, those are the x-intercepts of the function.
