Factorize and get the value of x and then substitute into any of the equation to get the solution in coordinate form (x, y)

<h3>Inequality functions</h3>

For us to determine if a set of inequality  function has a solution, we will equate the functions and determine the point of intersection if there are any,

Given the inequalities

y ≤ x^2 - 3

y > -x^2 + 2

Equate

x^2 - x = -x^2 + 2

Collect like terms

2x^2 - x - 2 = 0

In order to determine the value of x, we will factorize and get the value of x and then substitute into any of the equation to get the solution in coordinate form (x, y)

The vertex of this parabola is at (2.-3). When the yvalue is -2, the xvalue is 5. What is the coefficient of the squared term in
tatiyna

Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

y=a(x-h)^2+k,\text{ where (h,k) is vertex}

Plugging values of h and k, h= 2, k = -3

y=a(x-2)^2-3

Now, x=5, y=-2

-2=a(5-2)^2-3

-2=9a-3

9a=1

a=\frac{1}{9}

Thus, the coefficient of squared term is 1/9
