Answer:

d) y = (-3/4)(x - 3)^2 - 7

Explanation:

The vertex form of a quadratic function is:

y = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

We are given that the vertex is (3, -7), so we can substitute these values into the equation:

y = a(x - 3)^2 - 7

Now we need to find the value of "a". We can use the fact that the function passes through the point (1, -10). Substituting these values into the equation gives us:

-10 = a(1 - 3)^2 - 7

Simplifying, we get:

-10 = 4a - 7

-3 = 4a

a = -3/4

Substituting this value of "a" into the equation, we get:

y = (-3/4)(x - 3)^2 - 7

Therefore, the quadratic function in vertex form that can be represented by the graph that has a vertex at (3, -7) and passes through the point (1, -10) is:

y = (-3/4)(x - 3)^2 - 7
