Equation of a straight line on excel

[Tamara32479]

Hi! Would really appreciate any help basically I need to plot a graph from
an equation of a line. I havent got any data, just the equation. y=x squared+3
The graph should range from x=-4 to x=+4

Thank you

Hi,

Simplest thing is to use some cells to store a set of X values and then
calculate the Y's

Or try the ChtFrmla example on Stephen Bullen's page

Or Tushar Mehta's Plot Manager
