Write the equation of the parabola in vertex form.<br> vertex (3,1), point (2, - 6)<br> f(x) =?
Romashka [77]

Answer:

f(x)=-7(x-3)^2+1

Step-by-step explanation:

Vertex form of a quadratic is given by:

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

Where (h, k) is the vertex and <em>a</em> is the leading coefficient.

We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:

f(x)=a(x-3)^2+1

We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:

-6=a((2)-3)^2+1

Solve for <em>a</em>. Subtract:

-6=a(-1)^2+1

Simplify:

-6=a+1

Therefore:

a=-7

Hence, our quadratic is:

f(x) = -7 (x-3)^2 + 1
