Answer:
1) 3
2) 1
3) -5
Explanation:
The coefficients are the numbers that come before each variable.
The 3 in the first term is in front of the x^2; so the coefficient is 3.
There is no visible number in front of the y in the second term, but there is a y, so we can assume there's at least 1; so the coefficient is 1.
The term in front of x for the third term is -5, so the coefficient is -5.
