Question
Given f, left bracket, x, right bracket, equals, minus, 5, x, minus, 3f(x)=−5x−3, find f, left bracket, minus, 6, right bracketf(−6).
Solution
To find f(-6), we need to substitute -6 into the given equation for x.
Step 1: Replace x with -6 in the equation f(x) = -5x - 3.
f(-6) = -5(-6) - 3
Step 2: Simplify the equation.
f(-6) = 30 - 3
Step 3: Perform the subtraction.
f(-6) = 27
Therefore, f(-6) is equal to 27.
