When you graph a quadratic function , the y - intercept appears to be 1, and the x - intercepts appear to be -4 and 2.5 . Which values represent the solution ( s ) to the related equation of the function ? How can you check ? Explain .

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
