2) Linear : f(x) = x
Put it all together - Fill in the blank
f(x) represents a function. What happen when we do the following?
Shift up c units
y = f (x) + c _______________________________
Shift down c units
y = f (x) - c _______________________________
Shift right 3 units
y = f (x - c) ________________________________
Shift left 3 units
y = f (x + c) _______________________________
Reflects about the y-axis
y = f (-x) ________________________________
Reflects about the x-axis
y = - f (x) __________________________________
y   x3
Put it all together - Fill in the blank
f(x) represents a function. What happen when we do the following?
y = af (x) + c
if a is a number between 0 and 1( a fraction ) it stretches the graph horizontally
making it wider.
if a is greater than 1, then it compresses the graph. Making it taller.
