X^2+4x+5
(Find the vertex & axis symmetry) ~show steps~

Axis of symmetry is -2

vertex is (-2,1)

Step-by-step explanation:

Axis of symmetry is X=Negative b/2a

You need to find out the a, b, & c

a=1 (because when there is no number in front of x, it equals 1). b=4 and c=5

Place the a,b,&c into the formula x=-b/2a which is x= -4/2(1)

In the numerator, negative four is alone so it'll just be negative four.

in the denominator, 2*1 equals 2

Now you have -4/2 which is -2.

So the axis of symmetry is -2

To find the vertex you can simply put 1x^2+4x+5 into a graphing calculator. (I use desmos)

The vertex is the highest or lowest point of a parabola.

in this case, the parabola is a minimum

The vertex is (-2,1)

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
