Find the Vertex y=-7x^2+4

Problem

y=−7*x2+4

Solution

1. Identify the coefficients of the quadratic equation in the standard form y=a*x2+b*x+c

2. Determine the values of a b and c which are a=−7 b=0 and c=4

3. Calculate the x-coordinate of the vertex using the formula x=(−b)/(2*a)

x=(−0)/(2*(−7))

x=0

4. Substitute the x-coordinate back into the original equation to find the y-coordinate.

y=−7*(0)2+4

y=4

5. State the vertex as the ordered pair (x,y)

Final Answer

Vertex=(0,4)
