Problem

Use the displayed row to compare \(f(4)\) and \(g(4)\). Calculate the signed and absolute differences, then state what this one row cannot prove.

Clean source evidence without the requested comparison conclusion.

at x=4 = f(4)>g(4) because 20>15; signed difference = f(4)-g(4)=5; absolute difference = 5 units; limitation = one row does not determine slopes, intersections, or comparisons at other inputs

at x=4 = f(4)>g(4) because 20>15; signed difference = f(4)-g(4)=4; absolute difference = 4 units; limitation = one row determines every slope and intersection

at x=4 = g(4)>f(4) because 15<20; signed difference = g(4)-f(4)=-5; absolute difference = -5 units; limitation = one row proves g is greater elsewhere

at x=4 = f(4)>g(4) because 20>15; signed difference = f(4)-g(4)=5; absolute difference = 5 units; limitation = one row proves f is greater for all inputs
