Rewrite the equation of the parabola in vertex form. y= x2 + 8x - 21
sergey [27]

Answer:

y=(x+4)^{2}-37

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

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

where

(h,k) is the vertex of the parabola

if a> 0 then the parabola open upward (vertex is a minimum)

if a< 0 then the parabola open downward (vertex is a maximum)

In this problem we have

y=x^{2}+8x-21

Convert to vertex form

Complete the square

y+21=x^{2}+8x

y+21+16=(x^{2}+8x+16)

y+37=(x^{2}+8x+16)

y+37=(x+4)^{2}

y=(x+4)^{2}-37 --------> equation in vertex form

The vertex is the point (-4,-37)

the parabola open upward (vertex is a minimum)

Determine algebraically whether the function is even, odd, or neither. f(x = -5x2 4
Sunny_sXe [5.5K]
What you said doesn't even make sense.

I'll assume you said f(x) = -5x^2 + 4.

This is an even function.

f(-x) = f(x)
