Question

Given: f(x) sqrt 2x+5 and g(x) = 6x-3 find g(f(10)) and (f ∘g)(x)

Answer 1

g(f(10)) = g(sqr(2(10)+5) = g(sqr25)

= g(5) = 6(5)-3 = 30-3 = 27

fog(10) = f(g(10)) = f(6(10)-3) = f(60-3) = f(57) = sqr(2(57)+5) = sqr119

unless the last part was meant to read (fg)(10)

then

fg(10 = f(10)g(10) = 5(57) = 285

also the f(x) = sqr2x+5 is a little ambiguous

did you mean to write sqr(5x+5) or (sqr5x) +5?

the above calculations assume you meant sqr(5x+5)
