Does this graph represent a function? Why or why not? A. No, because it fails the vertical line test.
B. Yes, because it is a curved line.
C. Yes, because it passes the vertical line test.
D. No, because it is not a straight line.

C

Step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
