Answer:
Step-by-step explanation:
1. y= 1-x² is quadratic because has the variable x to the second power
y = -x² +1 has quadratic term -x², and constant term is 1
2. y= 3x-5 +4x²
a. quadratic term is 4x² because has the variable x to the second power
b. linear term is 3x because has the variable x to the power of one
c. constant term is -5 because the variable x to the power 0 so there is no x
