Question

If f(x) = 3x + 5 and g(x) = x - 1, then g[f(0)] = ?

Answer 1

\[f(x) = 3x + 5\]
\[g(x) = x-1\]
\[\text{Now all we have to do is to replace x of g with f(x)}\]
\[g(f(x)) = (3x + 5) -1 \]
\[\text{when x = 0}\]
\[g(f(0)) = 5 - 1 =4\]

Answer 2

Answer 3

\[f(0) = 3*0+5 = 5\]
\[g(f(0)) = g(5) = 5-1=4\]

Answer 4

the answer is 4
