Question

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

Answer 1

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
