Answer:
- Domain =

- Range =

Step-by-step explanation:
The given function is,

f(x) is a quadratic function. As this is a polynomial function, so its domain is the entire real number set.
As its leading coefficient will be negative, so it will open downward. Hence, its range will be all real numbers below its vertex.
The general vertex form of quadratic function or parabola is,

where (h, k) is the vertex.
Comparing the given function with this we get the vertex at 
The y coordinate of the vertex is -2, so the range of the given quadratic function is,

Answer:
The probability that no more than 70% would prefer to start their own business is 0.1423.
Step-by-step explanation:
We are given that a Gallup survey indicated that 72% of 18- to 29-year-olds, if given choice, would prefer to start their own business rather than work for someone else.
Let
= <u><em>sample proportion of people who prefer to start their own business</em></u>
The z-score probability distribution for the sample proportion is given by;
Z =
~ N(0,1)
where, p = population proportion who would prefer to start their own business = 72%
n = sample of 18-29 year-olds = 600
Now, the probability that no more than 70% would prefer to start their own business is given by = P(
70%)
P(
70%) = P(
) = P(Z
-1.07) = 1 - P(Z < 1.07)
= 1 - 0.8577 = <u>0.1423</u>
The above probability is calculated by looking at the value of x = 1.07 in the z table which has an area of 0.8577.
Answer: it is linear
Step-by-step explanation: A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1
