The answer to your question is letter b) 21

Step-by-step explanation:

Question: f(g(-1)) = ?

F(x) = 2x -3           g(x) = x2 + 11

f(g(x)) = 2(x2 + 11) -3             simplify

f(g(x) = 2x2 +22 - 3 = 2x2 +19    first result

f(g(-1)) = 2(-1)2 + 19      substitution

           = 2(1)  + 19       simplify

           = 2 + 19

            = 21                last result

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
