Find the values of b and c so g(x)=6x^2+bx+c has a vertex of (7,-9).

b = -84

c = 285

Step-by-step explanation:

Given that:

Vertex of (7, -9).

To find:

Value of b and c = ?

Solution:

It can be seen that the given equation is of a parabola.

Standard equation of a parabola is given as:

x coordinate of vertex is given as:

Here, A = 6, B = b and C = c, h = 7 and k = -9

So, the equation of given parabola becomes:

Now, putting the value of vertex in the equation to find c.

So, the answer is :

b = -84

c = 285

.
