(a)
Domain:
we know that domain is all possible values of x for which any function ios defined
Here, curve is defined for all values of x
so, domain is

Range:
Range is all possible values of y for which x is defined
minimum value of y is -4
maximium value of y is +inf
so, range is

(b)
x-intercept:
It is the value of x where f(x)=0
so, the point where curve intersects on x-axis
and we get


and

(c)
Increasing interval:
where curve is moving upward
we can see that

Decreasing interval:
where curve is moving downward
we get

Constant:
constant means horizontal line
there is no horizontal line here
so, it does not exist
(D)
End behavior:
when x-->+inf
y is moving upward
so, y---->+inf
when x-->-inf
y is moving upward
so, y---->+inf
(E)
we can see that curve jupms at x=-1
so, there is discontinuity at x=-1
and this is jump type of discontinuity
(F)
For odd:
f(-x)=-f(x)
For even:
f(-x)=f(x)
we can see that none of them holds true
so, this is neither

thanks thanks thanks thanks for your points
Step-by-step explanation:
Step-by-step explanation:

We have to simplify the given expression.

We know that:


Therefore, we get:




2x +4 (0)=12.4
2x=12.4
x=6.2
2(0) +4y=12.4
4y=12.4
y=3.1
Answer:
Mean = 10.2
Standard deviation = 4.0
Step-by-step explanation:
The average age = mean age
Mean = (16 + 10 + 5 + 7 + 13)/5
Mean = 51/5 = 10.2
What is the standard deviation will be square root of variance
(16 - 10.2) + (10 -10.2) + (5-10.2) + (7-10.2)+( 13-10.2)
5.8 + 0.2 -5.2 - 3.2 + 2.8
Square each number
33.64 + 0.04 + 27.04 + 10.24 + 7.84
Variance = 78.8/5 = 15.76
Standard deviation = 3.969 = 4.0
