The graphs of the functions f(x) = va and g(x) = x - 2 are shown in the xy-coordinate plane. When the equation v = x - 2 is solved by squaring both sides of the equation, the algebraic solutions to the squared
equation are x = 1 and x = 4. What do the graph of f and g reveal about the solutions?
8
y = f(x)
2),
y = g(x)
A) Both 1 and 4 are solutions
B) 4 is a solution but l is not
C) geither 1 nor 4 is a solution
D) there are two extraneous solutions
