Answer:
f(5) = 17
Explanation:
Function: f(x) = 3x + 2
x-value: 5
Equation: f(5) = 3(5) + 2
Solve:
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
Warning⚠
Many people thin that something like f(x) means that you are multiplying f and x. This is incorrect.
f(x) = 3x + 2 is the same as y = 3x + 2, the f is the name of the function, and you replace a number, like 5, for the x - value.
