Continue graphing f(x) = (x + 4)^2 by following these steps: | Steps: Step 1: Calculate the value of the function at the x-coordinate one unit to the left of the vertex. | Step 1: | Step 2: Plot the two points with x-coordinates one unit to the left and right of the vertex. | Step 2: | Step 3: Calculate the value of the function at the x-coordinate two units to the left of the vertex. | Step 3: | Step 4: Plot the two points with x-coordinates two units to the left and right of the vertex. | Step 4: | [(−6) =]
Substitute x = −6 into f(x) = (x + 4)²: f(−6) = (−6 + 4)² = (−2)² = 4. So the function value at x = −6 is 4, choice C.
