A cross-section of an irrigation canal is a parabola. If the surface of the water is 34 ft wide and the canal is deep at the center, how deep is it 9 ft from the edge?

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
