Given f(x) = 2root x+7 and g(x) = 5x^2 – 9, evaluate (f/g)(2) . I don't understand how to do this, can someone please explain the process??!! thanks!
grade 11 math -
I assume that you mean the function of a function, f[g(x)]
First calculate g(2)
g(2) = 5*4 - 9 = 11
Then calculate f(11)
Is f(x) = (2sqrtx)+7 or 2 sqrt(x+7) ?
I can't tell from the way your wrote it.
