Question

determine whether each function is linear or quadratic. identify the quadratic linear, and constant terms y=x+4

f(x)=x2-7

g(x)=-7(x-4)

y=x(1-x)-(1-x2)

Answer 1

please really need help

Answer 2

y=x+4 and g(x) and y=x(1-x)-(1-x^2)[=x-x^2-1+x^2=x-1] are linear
f(x) is quadratic

Answer 3

the numbers are the constant terms, the x is the linear term and the x^2 is the quadratic term
