Questions about the Exponential Functions poster

What’s on the Exponential Functions poster?

LINEAR against EXPONENTIAL, side by side. LINEAR: Add the same amount each step; LINEAR: y = mx + b; LINEAR: Constant difference; LINEAR: Graph is a straight line; LINEAR: Grows steadily forever; EXPONENTIAL: Multiply by the same factor each step; EXPONENTIAL: y = a · bˣ; EXPONENTIAL: Constant ratio; EXPONENTIAL: Graph curves upward sharply; EXPONENTIAL: Overtakes any linear function eventually; Check the differences: constant difference means linear, constant ratio means exponen…. b > 1 is growth. 0 < b < 1 is decay. b is never negative in these functions.

Who is the Exponential Functions poster for?

Exponential Functions is filed under 9th Grade (ages 14–15), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.

When should you use the Exponential Functions poster?

Compare a linear and an exponential table side by side. The crossover is dramatic. A wall chart earns its place by being glanceable from where the work is happening, so Exponential Functions belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.

What other posters go with Exponential Functions?

Absolute Value Equations, Arithmetic Sequences and Difference of Squares sit alongside Exponential Functions in the 9th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Absolute Value EquationsArithmetic SequencesDifference of Squares

Is the Exponential Functions poster free to download and print?

Yes. Exponential Functions downloads as a free PDF with no account, no email and no watermark, like everything else in the 9th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Exponential Functions poster print at?

Exponential Functions is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Exponential Functions loses nothing.Printing guide
