Best ResponseYou've already chosen the best response.1(f + g)(3) is short for f(3) + g(3) can you find f(3) ?

Best ResponseYou've already chosen the best response.1you mean f(3)= 27 (f(x) would be the formula 2x+21)

Best ResponseYou've already chosen the best response.0Given the functions f(x) = 10x + 25 and g(x) = x + 8, which of the following functions represents f[g(x)] correctly? f[g(x)] = 10x + 33 f[g(x)] = 10x2 + 33 f[g(x)] = 10x + 105 f[g(x)] = 10x2 + 105

Best ResponseYou've already chosen the best response.1yes the other way to do this is first add f(x)+g(x) like this: 2x + 21 + x24 and we get (f+g)(x)= 3x  3 now figure out (f+g)(3) = 3*33 = 9  3 = 6

Best ResponseYou've already chosen the best response.1starting with f(x) = 10x + 25 we can say f(a) = 10a+25 f(b*b)= 10*b*b+25 f(xyz)= 10*xyz+25 following that pattern, what is f( g(x) ) ?
