Answer:
a.
b.
Step-by-step explanation:
a. The equation of a polynomial can be written using its graph by finding the x-intercepts.
The graph has x-intercepts -4, 0, and 3. The x-intercepts are the solutions from the factors of the equation. -4 resulted from x+4. 0 resulted from x except at 0 it doesn't cross through. It touches meaning it has an even exponent likely . And 3 resulted from x-3. Putting these factors together is the equation in factored form.
b. If the function is shifted 2 units to the left then the x-intercepts become -6, -2, and 1. So the factors are .
When you round 4, 398, 202 to the nearest 100 it means to ignore the 4,398 and just look at 202. You could either round to 200 or 300 since you want to round to the nearest 100. Since the ones place is 2, you round the number to 200.
Answer: 4,398,200
Answer: A
Step-by-step explanation:
At 8 hours of service, the two limousine rental companies charge the same amount.
Step-by-step explanation:
Given,
Initial fee of Executive Limousine rental = $200
Per hour charges of service = $40
Let,
x be the number of hours.
E(x) = 40x+200
Initial fee of Jet Limousine rental = $120
Per hour charges of service = $50
J(x) = 50x + 120
For the charges to be same;
E(x) = J(x)
Dividing both sides by 10
At 8 hours of service, the two limousine rental companies charge the same amount.
