Unformatted text preview: Review Problems for the first exam in Math 135 Spring 2009. NOTE : These are only practice problems! The exam will cover all the material through section 3.5. 1. Find the equation of the line that passes through (2 , 4) and is perpendicular to the line 2 x + 3 y = 12. 2. Let f ( x ) = p x 2 + 2 x- 15 , g ( x ) = 1 x a) Find the domain of the function f ( x ). b) Find g ( f ( x )) and f ( g ( x )). c) Find the domains of g ( f ( x )) . 3. Find the exact value of each of the following limits. Show all work and/or give reasons for your answers: a) lim x → 2 x 2- 5 x + 6 x 2- 4 b) lim x → 4 x 2- 5 x + 6 x 2- 4 c) lim x → tan 2 x tan 7 x d) lim x → √ 3 + x- √ 3 x e) lim x → 3 | x- 3 | x- 3 f) lim x → 1- cos x x 2 4. Let g ( x ) = x 5 + x 3 +30. Without graphing the function g , use a theorem to show that there is at least one number c ∈ (- 2 , 2) such that g ( c ) = 0. HINT: don’t try to find c !...
