Name ______________________ Date: ___________ Logarithmic Functions HW #3 Introduction to BC Calculus Honors Mrs. Scala/Mr. Modiano Directions: For #1-10, solve each of the following equations for x. 1) 10 = 4e3 – 5x 2) e2x – 7ex + 10 = 0 3) log (x + 15) = 2 – log x 4) ln x + 5 = 6 + ln (2x + 3) 5) ln (x2 – 1) – 2ln (x – 1) = ln 7 6) 10 = 3e1 – 2x 7) e2x = 6ex – 8 8) log (x - 4) = 2 – log x 9) 5 ln (6x) = 20 10) ln (x2 – 1) – 2ln (x – 1) = 5 11) Find the domain of the function: f(x) = ln (x + 3) + ln (2x – 6). 12) Write the equation of a line that is perpendicular to 3x – 2y = 5 and passes through the point (3, -1). 13) Sketch the function: f(x) = - ln (x + 3) and then state the domain and range. 14) Is x + 2 a factor of the equation 3x4 – 2x2 + 4x – 48. ___________________________________________________________________________________________________________ If pro is opposite of con, then what is the opposite of progress? – J.
