1.1: RATIONALIZING DENOMINATOR • A radical expression with a square root in the denominator can be simplified by multiplying the numerator and denominator by the radical only. Fdgdfgdfgdfgdfg Ffff s
1.2: THE SLOPE OF A TANGENT • The slope of a tangent at a point (a, f(a)), can be found using the following formula: To find the slope: • Find the value of f(a) • Find the value of f(a + h) • Evaluate using the formula
1.3: THE RATE OF CHANGE • Used the AROC and IROC formula to solve rate of change problems. • Recall:
1.4: THE LIMITS OF A FUNCTION • The values of numbers around x can be used to find the limit. If the LHL (Left Hand Limit) = RHL (Right Hand limit), than L is the limit.
1.5: PROPERTIES OF LIMITS • Limits can be evaluated using some algebraically using the following properties of limits:
1.6: CONTINUITY • All polynomial functions are continuous for all real numbers. • A rational function h﴾x﴿ = f﴾x﴿ is continuous at x = a if g﴾a﴿ ≠ 0. • A rational function in simplified form has a discontinuity at the zeroes of the denominator. • When the one-sided limits are not equal to each other, then the limit at this point does not exist and the function is not continuous at this point.
