can someone help me evaluate these expressions please?

I’m not sure whether or not I’m suppose to plug in these given values. This is what it says in the book:

Given f(x) = √x and g(x) = x²-1, evaluate each expressions.

a)f(g(2))

b)g(f(1)

c)g(f(0)

d)f(g(2)

e) f(g(x)

f) g(f(x))

do what’s on the inside first, then the outside. so for ‘a’, start with g(2), which is 2^2-1=3. Now you have 3, plug that into the outside function, which gives f(3)=square root of 3. do the same for the rest.
