C
Step-by-step explanation:
This has a U like shape so it a parabola.
Parabola correlate with quadratic functions

Since it Going down, the answer is C -x^2.
Answer should be -4
since there is no other context, we can assume that x is -4.
Answer:
your answer should look like this.
Step-by-step explanation:
The horizontal line goes through y-intercept -1/2
C = 2 pi r
C = 2 x 3.14 x 5
C = 31.4 yd
A = pi r^2
A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 yd^2
