Buddy you're tryin' to draw the line For the m and the b we're assigned: Ain't hard you see, put your pencil on the b, One more point will guarantee that. ... We will, we will graph you! We will, we will graph you! So now you know the y-intercept; Here's how we find the rest of it: Up with rise, across for run, Plot another point, and when they're strung, sing... We have, we have graphed you! We have, we have graphed you! - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "We Will Graph you!" (quadratic version) by Larry Lesser You wanna draw a parabola From the general form algebra. Don't despair, complete the square: The x of the vertex comes out there, and We will, we will graph you! We will, we will graph you! The vertex now is figured out, But does the graph smile or frown? The number next to the square of x Gave the sign to make the sketch, now We will, we will graph you! We will, we will graph you! Find and plot any x-intercepts, The constant c is the y-intercept; A vertical line through the vertex Gives symmetry for your sketch, and We have, we have graphed you! We have, we have graphed you! |
