IGCSE Grade 10 Maths Linear functions transformations
|
To vertically stretch the function by a factor of 2, we multiply the coefficient of x by 2.
To horizontally stretch the function by a factor of 2, we divide x by 2
Translating k units up is equivalent to the function transformation , translating h units right is equivalent to the function transformation
Translating k units down is equivalent to the function transformation , translating h units left is equivalent to the function transformation .
Translation of k units up is equivalent to the function transformation
f(x+h)=Translate h units left
f(x–h)=Translate h units right
f(x)+k=Translate k units up
f(x)–k=Translate k units down
translation of h units right is equivalent to the function transformation
To reflect the function across the x-axis, we change the sign of the coefficient of x.
To reflect the function across the line y = 3x, we swap the x and y variables and change the sign of both coefficients.
To horizontally compress the function by a factor of 0.5, we multiply x by 2. And to reflect it across the y-axis, we change the sign of the coefficient of x
