I can’t see the image files you named. Please either upload the images or paste the functions and the stated domain and range here.
If you want to solve it yourself, here’s a quick checklist to match a function to a given domain and range:
1. Identify the function type:
- Polynomial (e.g., linear, quadratic): domain is all real numbers unless restricted; range depends on degree and vertex for quadratics (even-degree with positive leading coefficient has a minimum; negative leading coefficient has a maximum).
- Rational (p(x)/q(x)): domain excludes zeros of q(x); range often all reals except possible horizontal asymptote or value attained only by hole.
- Square root and even roots: require the inside ≥ 0 (if real-valued), so domain is where radicand ≥ 0; range is y ≥ 0 (or shifted).
- Logarithm: argument must be > 0, so domain is where inside > 0; range is all real numbers.
- Exponential: domain all real numbers; range (0, ∞) (or shifted/scaled accordingly).
- Trigonometric: standard domains/ranges (e.g., sin/cos domain all reals, range [-1,1]; tan domain excludes odd multiples of π/2, range all reals).
2. If the function is a graph:
- Domain = set of x-values that have corresponding points on the graph. Check whether endpoints are included (closed dot) or excluded (open dot).
- Range = set of y-values attained by the graph; again note open/closed endpoints and any asymptotes.
- For continuous intervals, note the min/max y-values; for unbounded up/down, range will be unbounded in that direction.
3. Common quick tests:
- If domain given is all real numbers, eliminate functions with denominators that could be zero, logs, even roots with restrictions, or any explicitly restricted piecewise domain.
- If range is (0, ∞), suspect an exponential or a squared function shifted up.
- If range is all reals but domain is restricted, look for functions that still produce every y in R from that domain (e.g., a line with slope ≠ 0 but domain restricted to all real x except a point?).
If you upload the images or list the function options, I’ll pick which one matches the given domain and range and show the reasoning.
