Determine if f(x, y)=10−x^2−y^2 is increasing or decreasing at (7,−3) if we take y to be constant and let x vary. Also determine if f(x, y) is increasing at (7,−3) if we take x to be constant and let y vary.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

yes   because as the functions are graphed they eventually will intersect unless otherwise
