Find the coordinates of the turning point for the equation of the graph below y=x^2+14x+45

(- 7, - 4 )

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the turning point is

x = -

y = x² + 14x + 45 ← is in standard form

with a = 1, b = 14 , then

x = - = - 7

Substitute x = - 7 into the equation and evaluate for y

y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4

coordinates of turning point = (- 7, - 4 )

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
