Answer: Part one! --- y=x^2+12x+27
Part two --- y=x^2+18x+80
Step-by-step explanation: For both of these questions, you have to work backwards to find the factors from the roots, then multiply the factors together! I know it looks like a long process, but really it's just turn around, back up, multiply and BOOM! Answer is there for. You just have to look at your signs, exponents and make sure you keep PEMDAS in order as well. All math basically requires PEMDAS. Like these questions right here that you asked! ☺
It's pretty easy but it takes a while to get a hang of it. I am still trying to get better at it as well but I am also trying to help you out!
I hope I helped you! Again! Haha! ☺
The answer is D. I am sure of this. Brainpower? Have a great day!
Answer:
3
Step-by-step explanation:
The first set is a function because each x-value has only one given y-value, the second funtion is a function because it is a quadratic equation, the third equation isn't a function because of the point of discontinuity at x=0 because of 1/0 being undefined, and the fourth equation is a linear function.
