Unformatted text preview: al, then f (x) is constant on the interval. f (b) - f (a) is the average rate of b-a change of the function f between x = a and x = b. x:a x:a x:c Average rate of change: lim+ f (x) is the limit as x approaches a from the right (x 7 a). x:a TEST TO FIND INTERVALS WHERE f (x) IS INCREASING/DECREASING 3. lim f (x) = f (c). Rate of Change and the Derivative lim f (x) is the limit as x approaches a from the left (x 6 a). Logarithmic Functions Domain: (0, q ) x:c x:a - Let y0 be the amount or number of some quantity initially present (t = 0). Then the amount present at any time t is y = y0ekt. If k 7 0, this is exponential growth and k is called the growth constant. If k 6 0, this is exponential decay and k is called the decay constant. 1. f (x) is continuous at x = c if 1. f (c) is defined. 2. lim f (x) exists. ONE SIDED LIMITS PROPERTIES OF LOGARITHMS FUNCTIONS 3. This means: 1. As x takes on values closer and closer (but not equal) to a on both sides of a, the corresponding values of f (x) get closer and closer to L. 2. The value of f (x) can be made as close to L as desired by taking values of x close enough to a. EXPONENTIAL GROWTH AND DECAY EQUATIONS OF LINES 1. parabola with a > 0 lim f (x) = L is read as “the limit of f (x) as x approaches a is L.” x:a PROPERTIES OF EXPONENTIAL FUNCTIONS Relative (Local) Extrema CONTINUITY AT x = c Instantaneous rate of change Slope of the tangent line Critical numbers, intervals of increase and decrease of a function, and relative extrema Marginal revenue, marginal profit, and marginal cost Velocity, v(t) 3 Find all critical numbers for f in (a, b). Evaluate f (x) for all critical numbers in (a, b) (ignore any critical numbers not within the given interval). Evaluate f (x) at the given endpoints of the interval, namely a and b. The largest value for f (x) is the absolute maximum and the smallest value for f (x) is the absolute minimum....
