The result is a shift upward or downward. Definition: Vertical Shift. Given a function f(x), a new function g(x) = f(x) + k, where k is a constant, is a vertical shift of the function f(x). All the output values change by k units. If k is positive, the graph will shift up. If k is negative, the graph will shift down.
Vertical Shift. If y = f(x) then the vertical shift is caused by adding a constant outside the function, f(x). Adding 10, like this y = f(x) + 10 causes a movement of +10 in the y-axis. Pay attention to the sign…. Vertical obeys the rules. Outside the function, a positive constant moves the function in the positive x-direction.

In determining an equation from a graph that involves a vertical shift, the value of A A will be half the distance between the maximum and minimum values: A = max − min 2 (9.3.4) (9.3.4) A = m a x − m i n 2. and the value of D D will be the average of the maximum and minimum values: D = max + min 2 (9.3.5) (9.3.5) D = m a x + m i n 2.
amplitude A = 2. period 2π/B = 2π/4 = π/2. phase shift = −0.5 (or 0.5 to the right) vertical shift D = 3. In words: the 2 tells us it will be 2 times taller than usual, so Amplitude = 2. the usual period is 2 π, but in our case that is "sped up" (made shorter) by the 4 in 4x, so Period = π/2. and the −0.5 means it will be shifted to ...
The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function. In other words, we add the same constant to the output value of the function regardless of the input. For a function g\left (x\right)=f\left (x\right)+k g(x) = f (x)+k, the function f ...
Vertical shifts correspond to the letter d in the general expression. If d is positive, the function will shift up by d units. If d is negative, the function will shift down by d units. Unlike horizontal shifts, you do not need to add d every time x shows up in the equation. To vertically shift a function, simply add d onto the end of the ...

Vertical shifts are a fundamental concept in the study of 1.2 Basic Classes of Functions, as they are a key component of function transformations. Understanding how vertical shifts affect the graphs of functions is crucial for being able to analyze, sketch, and interpret the behavior of various function families.
