The vertex of this parabola is at 2, -1 When the y-value is 0 the x value is 5 what is the coefficient of the squared term in th

Olegator [25]

Answer:

$\large \boxed{\sf \frac{1}{9}}$

Step-by-step explanation:

$\sf y=a(x-h)^2+k$

$\sf Vertex = (h,k)$

y-value is 0 and the x value is 5

h = 2

k = -1

$\sf 0=a(5-2)^2+-1$

Solve for $\sf a$ (the coefficient of the squared term).

$\sf 0=a(3)^2+-1$

$\sf 0=9a-1$

$\sf 9a=1$

$\displaystyle \sf a=\frac{1}{9}$

The coefficient of the squared term in the parabola equation is 1/9.
