(4x^5-15x^3-10x^2)-(2x^5-5x^3-2x^2)
So, the first thing we will do is add like terms. But before that, lets get rid of both parenthesis. We'll just get rid of the first pair, and for the second pair, we will multiple everything in the second parenthesis by -1
4x^5-15x^3-10x^2-2x^5+5x^3+2x^2
Now, we will add like terms.
2x^5-10x^3-8x^2
Now, there's a common factor that all of these terms share; it's 2x^2. 2x^5 can be divided by 2, as well as -10x^3 and -8x^2 (these are the coefficients, number found in front of the variable.) So, we'll distribute 2
2x^2(x^3-5x-4) (we take the 2x^2 out by dividing all terms by 2x^2)
So, our answer would be
2x^2
3yx-1
i think (the -1 is an exponent)
Answer:
No
Step-by-step explanation:
Answer:
5. not a function
6. function
7. not a function
8 function
9. not a function
10 function
Step-by-step explanation:
5. this fails the vertical line test. Since a vertical line would touch more than one point this is not a function
6. this is a function. Each input (or x) has only one output, so it is a function
7. This is not a function . X=2 goes to more than one y value x =2 goes to y=5 and y=6. so it is a relation not a function
8. this passes the vertical line test. Since a vertical line does not touch more than one point this is a function
9. This is not a function . X=5 goes to more than one y value x =5 goes to y=-4 and y=1. so it is a relation not a function
10. this is a function. Each input (or x) has only one output, so it is a function
