Step-by-step explanation:
to evaluate the composite function work from the inside out
first evaluate h(2) , then substitute the value obtained into g(x) then substitute the value obtained here into f(x)
h(2) = [tex]\frac{1}{2}[/tex] , then
g( [tex]\frac{1}{2}[/tex] ) = [tex]\sqrt{2(\frac{1}{2}) }[/tex] = [tex]\sqrt{1}[/tex] = 1 , then
f(1) = 1² - 1 = 1 - 1 = 0
