You can put this solution on YOUR website!
GIVEN:
\n" ); document.write( "g={(-8,-3), (-2,5), (1,0), (5,2)}
\n" ); document.write( "h(x)=2x+9
\n" ); document.write( "now what can be the following?
\n" ); document.write( "a. g^-1(5)=___
\n" ); document.write( "That is the x-value that goes with y = 5
\n" ); document.write( "Ans: -2
\n" ); document.write( "------------------------
\n" ); document.write( "b. h^-1(x)=___
\n" ); document.write( "That is the x-value that goes with x
\n" ); document.write( "Answer 2x+9
\n" ); document.write( "------------------------------\r
\n" ); document.write( "\n" ); document.write( "c. (h^-1 o h)(-8)=___
\n" ); document.write( "= h^-1[h(-8)]
\n" ); document.write( "=h^-1[-7]
\n" ); document.write( "That is the x-value that goes with y = -7:
\n" ); document.write( "-7 = 2x+9
\n" ); document.write( "2x = -16
\n" ); document.write( "x = -8
\n" ); document.write( "--
\n" ); document.write( "Ans: h^-1[-7] = -8
\n" ); document.write( "=======================
