Question 24

Multiple Choice

Find the domain and range and describe the level curves for the function f(x,y) .
-f(x, y) = Find the domain and range and describe the level curves for the function f(x,y) . -f(x, y) = A) Domain: all points in the xy-plane; range: all real numbers; level curves: parabolas y= cx<sup>2 </sup>- 6 B) Domain: all points in the xy-plane; range: real numbers z ≥ 0; level curves: parabolas y= cx<sup>2 </sup>- 6 C) Domain: all points in the xy-plane excluding x = 0; range: all real numbers; level curves: parabolas y= cx<sup>2 </sup>- 6 D) Domain: all points in the xy-plane excluding x = 0; range: real numbers z ≥ 0; level curves: parabolas y= cx<sup>2 </sup>- 6


A) Domain: all points in the xy-plane; range: all real numbers; level curves: parabolas y= cx2 - 6

B) Domain: all points in the xy-plane; range: real numbers z ≥ 0; level curves: parabolas y= cx2 - 6

C) Domain: all points in the xy-plane excluding x = 0; range: all real numbers; level curves: parabolas y= cx2 - 6

D) Domain: all points in the xy-plane excluding x = 0; range: real numbers z ≥ 0; level curves: parabolas y= cx2 - 6
