Calculus with Applications Summer Review Packet This packet is a review of the entering objectives for Calculus/Applications and is due on the first day back to school. Please show all work NEATLY and on a SEPARATE sheet of paper. Have a great summer!! 1. Simplify. Show work that leads to your answer. x3 8 b) x2 x4 a) 2 x 3x 4 5 x c) x 2 25 2. Trigonometric Pythagorean Identities: a) ______________ b) ______________ c) ______________ 3. Simplify each expression. Write answers with positive exponents where applicable: 1 1 a) xh x 1 f) log 100 2 2 b) x 10 x5 g) ln e 12 x 3 y 2 c) 18 xy 1 7 h) 27 2 3 2 3 3 2 5 3 d) (5a )( 4a ) e) (4a ) I) log 1 8 j) ln 1 3 2 2 4. Solve 4x + 10yz – 3 = 0 for z 5. Given: f(x) = {(3, 5), (2, 4), (1, 7)} a) h(g(x)) g ( x) x 3 h(x) = x 2 5 find, simplified: c) f -1 (x) (inverse) b) g(h(-2)) d) to find g-1 (x) (inverse) you switch _____ and then solve for _____. Fill in the blanks and then find the inverse. 5 6. Expand and simplify: 3n 6 n2 (remember means sum) 7. Using EITHER the slope/intercept (y = mx + b) or the point slope ( y y1 m( x x1 )) form of a line, write an equation for the lines described: SHOW ALL WORK a) with slope -2, containing the point (3, 4) b) containing the points (1, -3) and (-5, 2) c) with slope 0, containing the point (4, 2) d) parallel to 2x – 3y = 7 and passes through (5,1) e) perpendicular to the line in problem #7 a, containing the point (3, 4) 8. Without a calculator, determine the exact value of each expression: a) sin e) cos 2 3 b) sin 3 4 c) cos f) tan 7 4 g) tan 2 3 9. For each function: Make a neat sketch, putting numers on each axis For #d, e, f and g also write the equations of the asymptotes a) y = sin x 7 6 d) cos h) tan 2 Name the Domain and Range b) y x 3 2 x 2 3x c) y x 2 6 x 1 f) y e x d) y x4 x 1 e) y = ln x g) y 1 x h) y j) y x 3 2 k) y x2 4 x2 x4 i) y 3 x l) y x2 4 10. Make a neat sketch of the piecewise function: x 2 if x < 0 y = x + 2 if 0 < x < 3 4 if x > 3 11. Solve for x, where x is a real number. Show the work that leads to your solution: a) 2 x 2 5 x 3 b) ( x 5) 2 9 c) (x + 3)(x – 3) > 0 d) log x + log(x – 3) = 1 e) x 3 < 7 f) ln x = 2t – 3 g) 12 x 2 3 x h) 27 2 x 9 x 3 i) x 2 2 x 15 < 0 12.
