Part 1
Locate -2 on the x axis. Draw a vertical line until that vertical line crosses the parabola. Afterward, move left or right until reaching the y axis. After doing this, you should arrive at y = -3.
The input x = -2 leads to the output y = -3
Therefore C(-2) = -3 and we can state (-2,-3) is one point on the parabola.
Answer: -3
===========================================
Part 2
Follow similar steps as the previous part. This time we're on the y axis.
The parabola crosses the y axis at the location -1. This is the y intercept.
Answer: -1
===========================================
Part 3
The notation [C(-2)^4] is a bit strange. Did you mean to write [C(-2)]^4 instead? If so, then we raise the result of part 1 to the 4th power.
[C(-2)]^4 = [-3]^4 = 81
And also
[6*C(0)]^2 = [6*(-1)]^2 = [-6]^2 = 36
Then,
[C(-2)]^4*[6*C(0)]^2 = (81)*(36) = 2916
Answer: 2916
