Answer:
d. x ∈ {-3, -2, 1}
Step-by-step explanation:
The word "approximate" in the problem statement suggests that the roots may not be integers. Consequently, the solution method of choice is graphing.
A graph shows the solutions to f(x)=0 to be x=-3, x=-2, and x=1, matching selection D.

<em>Comment on the problem statement</em>
Any value of x can be put into the formula and it will be a "solution." For example, f(0) = -6 is a "solution" to the polynomial function. The problem statement is not specific as to the solution(s) sought. We have had to guess that we want values of x such that f(x)=0.
Answer:
The slope of this line would be 3.
Step-by-step explanation:
To find the slope of any line, use the slope formula and the points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(3 - 2)
m = 3/1
m = 3
Answer:
Correct option: (A) 43.48% fall in the price of a ticket.
Step-by-step explanation:
The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.
Given:
Price elasticity of demand = 0.23
% change in quantity demanded = 10
Compute the % change in price as follows:
Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.
Answer: 10 m/s
Step-by-step explanation:
Given
Momentum of boy 
Mass of boy is 
Momentum is the product of mass and velocity
Substitute value
Thus, the boy is moving with a velocity of 10 m/s
