128 Translations of Trigonometric Graphs• phase shift• vertical shift• midline
phase shift:
vertical shift:
midline: a horizontal reference line about which the graph of a trigonometric function .
• midline for parent functions: ______
• midline for functions vertically translated k units: ______
oscillates
Examples: State the amplitude, period, phase shift, and vertical shift of the function. Then graph the function.
1. y = sinθ + 4
Examples: State the amplitude, period, phase shift, and vertical shift of the function. Then graph the function.
2. y = cos(θ - 45o)
Examples: State the amplitude, period, phase shift, and vertical shift of the function. Then graph the function.
3. y =sin[(θ + 30o)] + 4
Examples: State the amplitude, period, phase shift, and vertical shift of the function. Then graph the function.
4. y =-2cos[3(θ -30o)] -4
