All you need to do is plug in some x values and find the correspoding y value
when x=0, y=-3
when x=1, y=9
when x=2, y=21
when x=-1, y=-15
Answer:
So 4th choice seems more accurate than others.
Step-by-step explanation:
Given function is
compare this formula with f(x)=a|x-h|+k, we get h=-4, k=-6
We know that vertex for above formula is given by (h,k) then vertex for given function will be (-4,-6)
which is different than given choice so first choice is not possible.
We see that 2/3 is multiplied outside of the parent function |x| so that will create vertical not horizontal compress so 2nd choice is wrong.
when value of a is positive the graph opens up. But we have a=-2/3 which is negative so graph will open down. Hence 3rd choice is wrong.
Absolute function will have domain, all real number so x<=-6 is part of that which is partially correct.
So 4th choice seems more accurate than others.
Answer : C
we need to the value of f(–1)
Table is given in the question
From the table ,
f(x) = 4 when x= -5, that is f(-5) = 4
f(x) = 0 when x= -1, that is f(-1) =0
f(x)= -1 when x=6, that is f(6) = -1
f(x)= -3 when x=9, that is f(9) = -3
So, the value of f(–1) = 0
