Answer:
Quadratic because the y values go up and then down. None of the other options can do that.
Answer:
x=64°
Step-by-step explanation:
x=180-90-26 (angles on a str line)
=64°
k = 5
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5
