Let f(x)= -4x+7 and g(x)= 10x-6. Find f(g(x)). <em>FYI: f(g(x)) can also be written as (f</em><span><em>○g)(x).
</em>What this really means is to take x and put it through g, then through f. Since we don't have a specific value for g, we can just put that x value through f, <em> </em>g(x) = 10x-6 f(x) = -4x+7 f(g(x)) = -4(g(x))+7 f(g(x)) = -4(10x-6)+7 f(g(x)) = -40x+24+7 f(g(x)) = -40x+31<em> </em></span>
