Answer:
a) Function:Yes
b) Domain: 
c) Range: 
Step-by-step explanation:
The given graph passes vertical line test hence it is a function
The given function has x-intercepts at 
We can therefore write this function in factored form as 
There is a y-intercept at (0,-2)
The required function is
b) The domain refers to all values of x for which this function is defined.
The domain from the graph is because there are holes at the end of the graph.
c) The range is the value of y for which x is defined or the graph exists.
From the graph the range is
profit, p = 6 × $50 = $300
losses, l = 120 + 30 + 200 = $350
overall = p - l = -$50
loss of $50
Answer:
y = 4x + 3
Step-by-step explanation:
To do this, put the new line into the form y = mx + b where m is the slope and b is the y-intercept.
When two lines are parallel, they have the same slope. Since, the slope of the first line is 4, that means the slope of the second line is also 4.
So far, the equation is y = 4x + b.
Then, since you know (-2, -5) is a solution, x = -2, y = -5 is a solution so you can plug this into the equation.
This would be:
-5 = 4 * -2 + b
-5 = -8 + b
3 = b
This means the equation is y = 4x + 3.
