Write the equation of the quadratic function f(x) that satisfies all three properties below: -
Contains the point (-4,-195), has the same shape as y=-3x², the x-coordinate of the vertex is 4.

As the vertex is at x = 4 and it is the same shape as y = -3x^2 the vertex of y = -3x^2 ( x = 0) moves 4 units to the right so the form of the f(x) is

f(x) = -3(x - 4)^2 + c where c is some constant.

Now when x = - 4 f(x) = -195 so:

-195 = -3(-4-4)^2 + c

-195 = -3*64 + c

c = -195 + 192 = -3.

So the required equation is f(x) = -3(x - 4)^2 - 3.

Write the equation of the quadratic function f(x) that satisfies all three properties below: - Contains the point (-4,-195), has the same shape as y=-3x², the x-coordinate of the vertex is 4.
