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

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.

Thank you.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
