Question

Graph the square root functions f(x)=x−2−−−−√ and g(x)=2−x−−−−√. Which function has a y-intercept? (1 point)Responsesf(x)f of xg(x)g of xboth f(x) and g(x)both f of x and g of x

Answer 1

g(x)

Reason: f(0) = √(0−2) = √(−2) (not real), so f has no y-intercept. g(0) = √(2−0) = √2, so g has the y-intercept (0, √2).
