Answer:
f(4) = 5
Step-by-step explanation:
f(x) = 5.
Whatever value of x you input to the function , the function's value is always 5.
This is seen when you examine the graph of f(x) = 5. It is a straight horizontal line passing through y = 5. For every value of x along the line, f(x) = y = 5.
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
So the terms are 9a, 4b, and 18.
