Answer:
C
Step-by-step explanation:
The zeros of a function are defined as the x-intercepts of the graph. The graphs touches or crosses the x-axis at -2, 0, and 4.
Answer:How do I round up one number how do I round up one number you word where not spell properly for the question
Step-by-step explanation:Rounding means making a number simpler but keeping its value close to what it was.
The result is less accurate, but easier to use.
round 73 is 70, 76 is 80
Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80.

Answer:
In mathematics, Fibonacci numbers, commonly referred to as Fₙ, form a sequence, called the Fibonacci sequence, so that each number is the sum of the previous two, starting with 0 and 1.
Step-by-step explanation:
Variables are difficult and confusing to me, but I get them enough to solve equations. For example, for some equations that I am doing now, they are; 2x^2 + 4x + 10, and there are variables that you can use for these. You could have, A(x)^2 + B(x) + C for your problem and you had to plug all of the variables in. A=2, B=4, C=10. Then you have your equation right there.
In real life, there are variables that you have to have for everyday life. If your job is in construction, or you are pouring concrete and you need volume or surface area, you would use a variable for the radius, r. When you buy gas and you want to figure your miles per gallon cost/ratio, your variable is simple. Say I drove 100 miles, and I have a 20 gallon tank and I want to figure out the miles per gallon. 100/20=x. Or if you don't know how many gallons go in your tank, it is 100/y=x. Then when you fill your vehicle up and you figure out how many gallons go into your tank, you eliminated both of your variables right then and there. 100/20=5.
When you go to grocery stores, the sales tax is the variable. Say you bought $95.34 worth of stuff, and you don't know your sales tax, that is your variable. $95.34 + x% = y. Then you figure out your sales tax, and you eliminated your variables, say your sales tax is 11.5%, move the decimal point to the left two times and you have your decimal, and multiply your number by it. Your sales tax is $10.96, and your total is $106.30.
So no matter how confusing and ridiculous variables seem, especially when you have super long problems that take 5 - 10 minutes to solve, variables are used in real life and they are important when you are doing a job that you are constantly using math and other things.
I do hope I helped you out.
