F(x) = 8x7 – x5 + x3 + 6
How many roots for this polynomial

Liz is shipping a package to her friend.the maximum weight of a medium flat-rate box is 20 pounds,including the box which weighs 6 ounces.write and solve an inequality to describe the possible weight ,w, of the contents that liz will ship to her friend if she must use a medium flat-rate box.

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
