Math 16A Short Calculus, section 2 Practice Midterm #1 Solutions 1. True/False Mark each question as ( T )rue or ( F )alse. a. T The line ( y - 3) = 2( x + 4) is in point-slope form. b. F If f ( x ) = 1 x and g ( x ) = 1 x 2 , then f g ( x ) = 1 x 3 . c. T If p ( x ) is a polynomial function and c is any real number, then lim x c p ( x ) = p ( c ). d. F Two lines are parallel if and only if their slopes are negative reciprocals of each other. e. F For any real number c , if f ( c ) is defined then f is contin- uous at c . f. T A function never intersects its vertical asymptotes. g. F The function x - 7 x - 7 has a vertical asymptote. h. T The general form of a circle is Ax 2 + Ay 2 + Dx + Ey + F = 0. i. T The graph of y = 2 x 2 + 2 passes through Quadrant II. j. F If an equation passes the horizontal line test, then the equation defines a function.
