The diagram is the graph of \(y = 6 + x - x^2\). The graph intercepts the x-axis at P and R and the y-axis at Q.
When \(y = 3\frac{1}{3}\), what is the positive value of x?
Attached Figure / Diagram
A
\( 2\frac{1}{2}\)
B
\( 2\frac{1}{5}\)
C
\( 1\frac{1}{5}\)
D
zero
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Draw a straight horizontal line across the y-axis at y = 3\(\frac{1}{3}\). let the line cut through the curve.
the points where the horizontal line meets the curve, trace it down to the x-axis to obtain the values of x when y = 3\(\frac{1}{3}\)
take only the positive value of x.
