2. yes, 4 (the highest degree is of the term 4x^4)
4. good! as long as 1/2x means 0.5* x and not 1 / (2*x)
6. Expanding x(x-1) = x^2 - x; the degree is 2 (from the term x^2)
8. good
10. good
State if it is a polynomial. If yes, say the degree.
2.f(x)=5x^2 +4x^4
4.f(x)=3-(1/2x)
6.f(x)=x(x-1)
8.f(x)=sqaure oot of x (square root of x-1)
10.f(x)=(x^2-5)/x^3
12. f(x)=-3x^2(x+2)^3

Thanks, so is the degree all of the x added together or jut the greatst one bcause tthen wouldnt 12 be 3 instead of 5?
greatest power of x. No on your comment on 12.
you have x^2(x+..)^3= x^2*(x^3+...) or hightest degree will be x^5
you have x^2(x+..)^3= x^2*(x^3+...) or hightest degree will be x^5
ohhhh gotcha thanks!!
