Card 1 of 23

State the two conditions required for a sign change between x=ax=ax=a and x=bx=bx=b to guarantee at least one root.

A
  • The function f(x)f(x)f(x) is continuous on [a,b][a,b][a,b]
  • f(a)f(a)f(a) and f(b)f(b)f(b) have opposite signs
B
  • The function f(x)f(x)f(x) is discontinuous on [a,b][a,b][a,b]
  • f(a)f(a)f(a) and f(b)f(b)f(b) have opposite signs
C
  • The function f(x)f(x)f(x) is continuous on [a,b][a,b][a,b]
  • f(a)f(a)f(a) and f(b)f(b)f(b) have the same sign
D
  • The function f(x)f(x)f(x) is continuous on (a,b)(a,b)(a,b)
  • f(a)f(a)f(a) and f(b)f(b)f(b) are equal
