Question 1137770


{{{f(x) = x^4 + 5x + 2}}}, {{{-1 <= x <=1}}},{{{ y }}}= {{{-1}}}, {{{0}}}, {{{1 }}}


{{{ graph( 600, 600, -5, 5, -10, 50, x^4 + 5x + 2) }}}


first find 
{{{y=-1}}} ({{{x}}}, {{{y}}})= ({{{-0.6}}},{{{-1}}}) since given {{{-1 <= x <=1}}}
{{{y=0}}} ({{{x}}}, {{{y}}})=({{{ -0.4}}},{{{ 0}}})
{{{y=1}}} ({{{x}}}, {{{y}}})= ({{{-0.2}}} , {{{1}}})

recall: The inverse of a function has all the same points as the original function, except that the x's and y's have been reversed. 

 ({{{-0.6}}}, {{{-1}}})=> inverse is ({{{-1}}},{{{-0.6}}})

 ({{{ -0.4}}},{{{ 0}}})=> inverse is  ({{{0}}},{{{-0.4}}})

({{{-0.2 }}},{{{ 1}}})=> inverse is ({{{1}}},{{{-0.2}}})
