For what values of x is the function NOT continuous

Let f be a function defined as follows: f (x) = sin x, x x^2 , 0 ≤ x 2 − x, 1 ≤ x x − 3, x ≥ 2 For what values of x is f not continuous? Should I find f(0) and f(1) and f(2) then find the limit

Parametrize x and y from 2x^2+xy+y^2=4 as one variable "t"

x=sqrt(2)cos(t)-(1/sqrt(8))sint y=2.1sin(t)-(1/8)cos(t) This is close but not exact.Ive really just been doing guess and check because I have no idea how to solve it.-By completing the square in y,

Write an equivalent expression without using grouping symbols.–(−9x3 + 8x + 10) I dont know where to start!!

since there are no like terms or anything all you have to do is change everything to the opposite of what it is because of the negative thats outside of the parenthesis. so your answer would be 9x3 -
