Step-by-step explanation:
I THINK THE BUILDING IS 6X TALLER THAN A PERSON
The graph would be a vertical line through x=1 (1,0), with shading to the left of it.
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
