Hi guys,
New here and I'm hoping someone may be able to help me?
I need to graph the following equation in excel and I can't remember how to do it?
y=6x(squared)+3x-18
I'd really appreciate any help you can give me
Thanks

Hello,
here's how I would have done :
I would have created a column named $\displaystyle x$ in A1. In A2, I put "=-20". Then, in A3, I put "=A2 + 1". Then I use the quick formula copy, so that I get a column of $\displaystyle -20 \leq x \leq 20$. Then, in B1, I put $\displaystyle f(x)$, and in B2 I write "=6*A2*A2 + 3*A2 -18. Then I use the quick formula copy to extend the column $\displaystyle f(x)$ as far as the column $\displaystyle x$ goes. Thus I get two sets of data, $\displaystyle x$ and $\displaystyle f(x)$, which I can plot using the graph wizard
