let f(x)=4x-1 and g(x)=x^2-5
(f∘g)(7)=
To find (f∘g)(7), we first need to find g(7) and then substitute that value into f(x).
Starting with g(x)=x^2-5, we substitute x=7:
g(7) = 7^2 - 5
= 49 - 5
= 44
Now we substitute g(7) into f(x)=4x-1:
f(g(7)) = f(44)
= 4(44) - 1
= 176 - 1
= 175
Therefore, (f∘g)(7) = 175.
