The value of (fog)(2) is 93
What is a function?
A function is an expression that shows relationship between two variables, an independent and dependent variable.
If f(x) = 2x² - 5
g(x) = 3x + 1
To determine g(x), we substitute the value of x as 2
g(x) = 3x + 1
g(2) = 3 (2) + 1
g(2) = 7
(fog)(2), substitute the value of x as 7, we get;
(fog)(2) = 2x² -5
(fog)(2) = 2 (7)² - 5
Find the square
(fog)(2) = 2(49) - 5
(fog)(2) = 98 - 5
(fog)(2) = 93
Thus, the value of (fog)(2) is 93
