I can’t see the attached images. Could you either re-upload the graph or describe it (shape, key points, vertex or corner, asymptotes, where it crosses the axes, and whether it opens up/down or left/right)?
To help you finish this yourself, here’s a quick step-by-step method for identifying the transformed function (works for absolute value, parabola, square root, exponential, reciprocal, etc.):
1. Identify the parent shape f(x)
- V shape → absolute value |x|
- U-shaped parabola → x^2
- One-sided curve starting at a point → √x
- Two-branch hyperbola → 1/x
- Rapidly growing/decaying curve → e^x or a^x
- Horizontal/vertical asymptote gives exponential or reciprocal clues
2. Put the answer in the general transformed form
y = a · f(b(x − h)) + k
- h = horizontal shift (right if h>0)
- k = vertical shift (up if k>0)
- a < 0 means reflection across x-axis (flip vertically)
- b < 0 means reflection across y-axis (flip horizontally)
- |a| > 1 vertical stretch, 0<|a|<1 vertical compression
- |b| > 1 horizontal compression, 0<|b|<1 horizontal stretch
3. Find h and k from the graph’s key point
- For |x| or x^2, use the vertex/corner location (h,k).
- For √x, use the starting point of the curve (h,k).
- For 1/x, use the center of symmetry / location of asymptotes.
4. Determine a and b using one or two additional points
- Plug a known point (x,y) into y = a·f(b(x−h))+k and solve for a (and b if needed).
- If you can see a slope-like steepness change, that gives |a| or |b|.
Examples
- If the graph is a downward V with corner at (3, −2): y = −|x − 3| − 2
- If it’s a parabola opening downward with vertex at (1,4) and wider than y=x^2: y = −(1/2)(x − 1)^2 + 4
- If it’s a square-root starting at (4,1) and flipped downward: y = −√(x − 4) + 1
If you describe the graph (shape and at least one or two clear points or the vertex/corner/asymptotes), I’ll give the exact function.
