Given f(x) = 4(3 – X), what is the value of f(-5)?
Hi there.
To find the value of f(-5), we need to substitute x = -5 in the equation.
Now then, know the basic rules of multiplying in the negative.
When you multiply the negative with the negative, you will get the positive.
Thus, - (-5) = 5
Then distribute 4 inside.
Therefore, the answer is f(-5) = 32
