Answer:
i)D:
ii)R: 
iii) Y-int:(0,-1)
Step-by-step explanation:
i) The given absolute value function is;
.
The absolute value function is defined for all real values of x.
The domain is all real numbers.
ii) The range is all y-values that will make x defined.
The given function,
.
has vertex at, (-2,-3) and opens upwards.
This implies that, the minimum y-value is -3.
The range is
iii) To find the y-intercept substitute x=0 in to the function.
.
.
.
.
The y-intercept is (0,-1)
See attachment for graph.
The greatest common factor is the biggest thing that they all share... If we look at it they all have 4 as their coefficients so you can take that out but they also have a squared so you can take that out too so the GCF if 4a squared... but No x because one of them doesn't have it... all of them have to have it in common.
Answer:
-2/3= x
Step-by-step explanation:
<u><em>square all the terms on both sides to get rid of the radicals:</em></u>
<u><em>exponent 2 and the radical cancel each other:</em></u>
1 + 1 - x = 2x + 4
2 - x = 2x + 4
<u><em>like terms on each side ( when you move one term tp the other side, it changes its sign ):</em></u>
2-x = 2x+4
2-4 = +x +2x
-2 = 3x
<u><em>now to keep the x alone, divide both sides by 3:</em></u>
-2/3 = 3x/3
-2/3= x
Yes, it is Proportional.
Y=0.25x
For example:
If x=1, y=0.25
If x=2, y=0.5
So, it is proportional.
Answer:
you can use desmos
Step-by-step explanation:
for example put x=88
and do the same with the rest
then put x+y+z and you will get your answer
