Answer:
225%
Step-by-step explanation:
You can figure the percentage change from ...
percentage change = ((new value)/(old value) -1) × 100%
= (26/8 -1) × 100% = (3.25 -1) × 100% = 225%
You do this by converting to vertex form a(x - b)^2 + c where the axis of symmetry is x = b
the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one
x^2 - 6x - 1 = (x - 3)^2 -9-1
the last option is the correct one
A linear function is y=mx + b so yes (assuming + sign at end is accidental)
(2x10)+15= 35
There are two 10s and one 15
20+15=35
