The value of f(3) in the given function is 10
What is the function of a f(x)?
The function of f(x) means the expression in x to get a desired result. The function of f(x) relates to y = f(x), and for each value of x, there is a value for y.
From the given information:
f(x) = -x² - 4x + 13
For determine f(3), we will replace the value of x in previous equation with (3)
f(3) = (-3)² -4(3) + 13
f(3) = 9 - 12 + 13
f(3) = 10
