i need help with these Algerbra 2 Questions.....?

Question

Determine whether each function is linear or quadratic. Identify the quadratic,linear, and constant terms.
1.y = x + 4
2. y = 2x2 - (3x - 5)
3. y = 3x(x - 2)
4.f(x) = x2 – 7
5.y = (x - 2)(x + 5)
6.g(x) = -7(x - 4)
7.h(x) = (3x)(2x) + 6
8. y = x(1 - x) - (1 - x2) 9. f(x) = -x(2x + 8)

Answer 1

doofus, make it 2x^2 so it makes sense

1. linear
2. quadratic
3. quadratic
4. quadratic
5. quadratic
6. linear
7. quadratic
8. quadratic
9. quadratic

not iding all, but the squares are the quadratic terms, the xs are linear and without a variable is the constant

Answer 2

linear, if it forms a line,

quadratic: if it's squared.

Constants are numbers without variables.
Quadratic, linear, I think you list the entire term that is sqaured or not.

Answer 3

its simple this way.
equations which have only constant ( no variable) is constant
equations which have x^2 as highest degree is quadratic
equaitons which have x^3 as highest degree is cubic..
x= is independent variable.
