The function y = x^2 - 4x + 5 approximates the height, y, of a bird, and its
Soloha48 [4]

Answer:

Option C and option D

Step-by-step explanation:

we have that

y=x^{2}-4x+5

This is the equation of a vertical parabola open upward

The vertex is a minimum

Convert the equation into vertex form

Complete the square

y-5=x^{2}-4x

y-5+4=x^{2}-4x+4

y-1=x^{2}-4x+4

y-1=(x-2)^{2}

y=(x-2)^{2}+1 ----> equation of the parabola in vertex form

The vertex is the point (2,1)

therefore

when the bird is 2 feet away from the first fence post, it reaches its minimum height of 1 foot
