Q. f(x)=8x3+5h(x)=3x−5Write (h∘f)(x) as an expression in terms of x.(h∘f)(x)=
Understand h@f(x): First, we need to understand that (h@f)(x) means h(f(x)). This means we will substitute the function f(x) into the function h(x) wherever there is an x.
Substitute f(x) in h(x): The function f(x) is given as f(x)=8x3+5. We will substitute this expression for x in the function h(x).
Replace x with f(x): The function h(x) is given as h(x)=3x−5. Now we will replace x with f(x) to get h(f(x)).h(f(x))=3f(x)−5
Substitute f(x) in h(f(x)): Substitute f(x)=8x3+5 into the expression for h(f(x)):h(f(x))=3(8x3+5)−5
Simplify expression inside cube root: Simplify the expression inside the cube root:h(f(x))=38x3+5−5h(f(x))=38x3
Take cube root of 8x3: Now, we take the cube root of 8x3: h(f(x))=38x3 h(f(x))=2x
