Question 1187171


Find the x-intercepts (horizontal intercepts) of the function:

{{{f(x)=4abs(x-3)-1}}}

set {{{f(x)=0}}}

{{{0=4abs(x-3)-1}}}

{{{0=4abs(x-3)-1}}}......................recall that {{{abs(x-3) =sqrt((x - 3)^2)}}} 

{{{0=4(x-3)-1}}}
{{{0=4x-12-1}}}
{{{0=4x-13}}}
{{{13=4x}}}
{{{x = 13/4}}}

and
{{{0=4(-(x-3))-1}}}
{{{0=4(-x+3)-1}}}
{{{0=-4x+12-1}}}
{{{0=-4x+11}}}
{{{4x=11}}}
{{{x = 11/4}}}

The intercepts are at{{{ x = 11/4}}} and {{{x = 13/4}}}
