Try them, get help one step at a time, then print how it went.
Practice: try it, then get help one step at a time
Reading a and b, building tables, evaluating with function notation, and comparing members. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card. Power first, then multiply by a.
My results
Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.
Exit ticket
On paper or an index card. Use the math word and the plain-English word.
- For y = 6 · 4x, what are a and b, and what does each do?
- Why is a the y-intercept of y = a · bx?
- f(x) = 2 · 5x. Find f(0) and f(3).
- x: 0, 1, 2 and y: 4, 12, 36. Write the equation.

- a = 6: starting value and y-intercept. b = 4: multiply by 4 each step.
- At x = 0, b0 = 1, so y = a · 1 = a.
- f(0) = 2. f(3) = 2 · 125 = 250 (power first).
- a = 4, b = 3: y = 4 · 3x.
