    and then hears how you do the 2nd part of your problem Let's solve for g. gx=10x−6 Step 1: Divide both sides by x. gxx=10x−6x g=10x−6x Answer: g=10x−6x

    solve for \(g\)??!! darling, \(g\) is not a variable \(g(x)\) is a function it is \[g(x)=10x-6\]

    \[f(x)=-4x+7\\ g(x)=10x-6\] so \[f(g(x))=f(10x-6)\] is the first step

    then since \[\huge f(\clubsuit)=-4\clubsuit +7\] you have \[\huge f(10x-6)=-4(10x-6)+7\]

    a little algebra will clean that up nicely
