Curve Sketching

A. Sketch a graph of the function \( f \) that satisfies all of the following conditions.

(a) \( f(-4)=0 \) and \( f(0)=3 \)

(b) \( \displaystyle\lim_{x\to4^-} f(x) = -\infty \) and \( \displaystyle\lim_{x\to4^+} f(x) = \infty \)

(c) \( \displaystyle\lim_{x\to\infty} f(x) = 2 \)

(d) \( f'(x) > 0 \) on \( (-\infty, 0) \)

(e) \( f'(x) < 0 \) on \( (0,4) \) and \( (4,\infty) \)

solution

B. Sketch a graph of the function \( f \) that satisfies all of the following conditions.

(a) \( f(-2)=0 \), \( f'(-2)=0 \), and \( f(0)=3 \)

(b) \( f'(x) < 0 \) on \((-\infty,-2)\), and \( f'(x) > 0 \) on \((-2,0)\)

(c) \( f''(x) > 0 \) on \((-\infty,-1)\), and \( f''(x) < 0 \) on \((-1,1)\)

(d) The graph has y-axis symmetry.

C. Sketch the graph of the function \( f \) that satisfies the given conditions.
