Given the functions:
g(x) = x^2 + 3
h(x) = 2x + 1
A. Find g(4)
B. Find h(11)
Solution:
A. g(4)
In order to find the value of g(4), we substitute the value of 4 to each variable x.
g(x) = x^2 + 3
g(4) = 4^2 + 3
g(4) = 16 + 3
g(4) = 19
The value of g(4) = 19
B. h(11)
In order to find the value of h(11), we substitute the value of 11 to each variable x.
h(x) = 2x + 1
h(11) = 2(11) + 1
h(11) = 22 + 1
h(11) = 23
The value of h(11) = 23
