The solution for f(3) in the function f(x) = 7x² - 2x is 57
From the question, we have the following equation that can be used in our computation:
F(X) = 7x2-2x
To make the equation legible, we need to rewrite it
So, we have the following representation
f(x) = 7x² - 2x
Also from the question, we have
f(3)
This means that the value of x is 3, and we calculate f(x) when x = 3
Substitute the known values in the above equation, so, we have the following representation
f(3) = 7x² - 2x
So, we have the following equation
f(3) = 7(3)² - 2(3)
There are constants to add or subtract to both sides of the equation
So, we have the following representation
f(3) = 57
Hence, the solution is 57
