Using the graph at right of f(x), sketch the following functions (draw each on a separate grid). Homework Help ✎
f(x) + 2
2f(x + 1)
−f(x − 2)
The function value, f(x), is the y-value. How does the graph change if 2 is added to each y-value?
New function: If x = 1, f(new) is equivalent to f(2) from the original function. Also, what does multiplication by 2 do to the function?
See part (b). Also, f(x) became −f(x), or y became −y.
f(8) in the original function occurs
when x = 4 in the new function.
