Question

Find coordinates of the vertex for the parabola defined by the given quadratic function.

f(x)=4x^2+16x+10

Answer 1

well find the line of symmetry using

\[x = \frac{-b}{2a}\]

the vertex is on the line of symmetry...

so in your question a = 4 and b = 16

when you have a value for x.... substitute it into the equation to find the vertex
