The graph of the parent function is horizontally stretched by a factor of ⇒ 1st answer
Step-by-step explanation:
Let us revise some transformation
A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis.
A horizontal stretching is the stretching of the graph away from the y-axis
- If k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally shrunk (or compressed) by dividing each of its x-coordinates by k.
- If 0 < k < 1 (a fraction), the graph of y = f(k•x) is the graph of f(x) horizontally stretched by dividing each of its x-coordinates by k
- If k should be negative, the horizontal stretch or shrink is followed by a reflection across the y-axis
A vertical stretching is the stretching of the graph away from the
x-axis
A vertical compression (or shrinking) is the squeezing of the graph toward the x-axis.
- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched by multiplying each of its y-coordinates by k.
- If 0 < k < 1 (a fraction), the graph of y = k•f(x) is the graph of f(x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k
- If k should be negative, the vertical stretch or shrink is followed by a reflection across the x-axis.
∵ is a parent function
∵ Its graph transformed to produce the graph of
- That means x is multiplied by a factor k, then it is compressed
or stretched horizontally
∵ k =
- The factor is between 0 and 1, then it is
stretched horizontally as the second rule above
∴ The graph of the parent function is stretched horizontally by a
factor of
The graph of the parent function is horizontally stretched by a factor of
