Answer:
g(3) = 7
Step-by-step explanation:
g(3) means to substitute "x" for 3.
Change any "x" in the function to 3. Then solve.
Take the function
g(x) = 2x + 1
Substitute x = 3
g(3) = 2(3) + 1
Solve with BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).
g(3) = 2(3) + 1 Multiply first
g(3) = 6 + 1 Add
g(3) = 7 Answer
