In Exercises 55 - 68, (a) state the domain of the function, (b) identify all intercepts, (c) identify any vertical and slant asymptotes, and (d) plot additional solution points as needed to sketch the graph of the rational function. \( f(x) = \dfrac{2x^2 - 5x + 5}{x - 2} \)
When two resistors of resistances \( R_1 \) and \( R_2 \) are connected in parallel (see figure), the total resistance \( R \) satisfies the equation \( \dfrac{1}{R} = \dfrac{1}{R_1} + \dfrac{1}{R_2} \) Find \( R_1 \) for a parallel circuit in which \( R_2 = 2 \) ohms and \( R \) must be at least \( 1 \) ohm.
In Exercises 83 - 86, (a) find the interval(s) for \( b \) such that the equation has at least one real solution and (b) write a conjecture about the interval(s) based on the values of the coefficients. \( x^2 + bx - 4 = 0 \)
In Exercises 13 - 30, solve the inequality and graph the solution on the real number line. \( -2x^2 + 6x + 15 \le 20 \)
In Exercises 55 - 68, (a) state the domain of the function, (b) identify all intercepts, (c) identify any vertical and slant asymptotes, and (d) plot additional solution points as needed to sketch the graph of the rational function. \( f(x) = \dfrac{2x^3 + x^2 - 8x - 4}{x^2 - 3x + 2} \)
