Best ResponseYou've already chosen the best response.0you just want to plug in " x = 4" for each of the functions :) Let's start with \[e(x) = x^2 + 6x + 21\] So when we replace all the x's with 4, we get this equation. \[e(4) = 4^2 + 6(4) + 21 = ?\]

Best ResponseYou've already chosen the best response.0yep :) good job! so, e(4) = 61 Now we do the same thing with the other functions :) \[m(x) = 8x \] plug in x = 4 and we get: \[m(4) = 8(4) = ?\]

Best ResponseYou've already chosen the best response.0yes good! Now next function: \[v(x) = 31(x)\] plug in x = 4 \[v(4) = 31(4) = ?\]

Best ResponseYou've already chosen the best response.0not quite... we already worked out what EACH function equals when x = 4, e(4) = 61 m(4) = 32 v(4) = 124 So which one is has the largest value?

Best ResponseYou've already chosen the best response.0yesss so that means v(x) would be the largest function when x = 4
