If the graph of F"(x) is continuous and has a relative maximum at x = C, which of the following must be true? (5 points) None of the above is necessarily true.

The graph of f has an inflection point at x = c.

The graph of f has an x-intercept at x = 0

The graph of f has a relative minimum at x = 0​

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
