I submitted my question earlier, but need to have an answer in the next 20 minutes. My question is as follows, and is not out of textbook: What are the intercepts and coordinates of x,y, and the domain from the equation f(x) = 4x^5 +3x^4 - 2x^2 + 7?
Rewrite the equation 2x – 3y = –6 as a function of x
Can someone please show me how to do this.
thanks
