## Resource summary

 Question Answer Reciprocal graphs e.g. y = 1 / x Reciprocal-square graphs e.g. y = 1 / x^2 Reciprocal-square graphs y = 1 / x^2 Straight line graphs e.g. y = x Straight line graphs y = x Quadratic graphs e.g. y = x^2 Cubic graphs e.g. y = x^3 - x Quadratic graphs y = x^2 f(2x) Stretch by a factor of 0.5 horizontally (Shrink by half) Cubic graphs y = x^3 - x f(0.5x) Stretch by a factor of 2 horizontally Bad guy x lives in bracket prison, whatever you tell him to do he does the opposite. Good guy y lives outside bracket prison and does what he's told. f(x + 2) Move 2 to the left f(2x) You: "Stretch twice as wide!" X: "No." X: *becomes half as wide* f(x - 2) Move 2 to the right f(0.5x) You: "Shrink to half your size!" X: "No." X: *becomes twice as wide* f(-x) Flip in the y axis f(x+2) You: "Move 2 to the right!" X: "No." X: *Moves 2 to the left* f(x-2) You: "Move 2 to the left!" X: "No." X: *Moves 2 to the right* The only thing x does right is this: f(-x) because he can't do anything else You: "Flip sideways!" X: "..." X: *Flips sideways* 2f(x) You: "Stretch up high!" Y: "Okay, how high? 2? Got it." Y: *Stretches up by 2* 0.5f(x) You: "Compress down!" Y: "Okay, by how much? Half? Got it." Y: *Compresses down* f(x)+2 f(x)-2 You: "Move 2 to the left!" Y: "Okay, by how much? Half? Got it." Y: *Compresses down* 2f(x) Stretch by a factor of 2 vertically 0.5f(x) Stretch by a factor of 0.5 f(x) + 2 Move 2 upwards f(x) - 2 Move 2 downwards -f(x) Flip in the x axis
