Question

Find the Y coordinate of the vertex of the PA RK be OLA who’s equation is why equals X2 minus X +2. A is one and three fourths B is two and C is 2 1/4

Answer 1

Answer

A) one and three fourths

Step by step explanation

y = x^2 - x + 2

Here we have to use the formula.

The x coordinate of the vertex = -b/2a

Compare the given equation  y = x^2 - x + 2 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"

Here a = 1 and b = -1

Vertex of x coordinate = -b/2a, now plug in the value of a and b, we get

x = - (-1)/2(1)

x = 1/2

Now we have to find the y-coordinate of vertex.

Now plug in x = 1/2 in the given equation, we get

y = (1/2)^2 - 1/2 + 2

y = 1/4 - 1/2 + 2

y = 1 3/4

That is one and three fourths.

The answer is A) one and three fourths.
