URGENT I HAVE ALMOST 0 TIME LEFT I NEED LAST MINUTE HELP
jonny [76]

Answer:

The zeros are the points where the parabola intercepts the x-axis.

\sf x = 7 \implies x - 7 = 0

\sf x = 1 \implies x - 1 = 0

\sf \implies y = a(x - 7)(x - 1)  where a is some constant

If the parabola passes through point (3, 4) then:

\sf \implies a(3 - 7)(3 - 1) = 4

\sf \implies a(-4)(2) = 4

\sf \implies -8a = 4

\sf \implies a = -\dfrac12

So the equation of the parabola is:

\sf y = -\dfrac12(x - 7)(x - 1)

Or in standard form:

\sf y = -\dfrac12x^2+4x-\dfrac72
