  Calculus 1: exercises
  
  This is a set of exercises for Calculus 1: course.
  
  • Let $h(x)=x²+3x-10$. Find the $x$- and $y$-intercepts and sketch the graph of the function.
  • Sketch the graph of a function f that has the following property: f is increasing and concave down on $[-1,1]$.
  • Find the formulas (only) of the inverses of the following functions: 1. $f(x)=(x+1)³$. 2. $g(x)=\ln (x³)$.
  • $f′(x)=(e^{x})².$ (a) On what intervals, if any, if f increasing? (b) On which intervals, if any, is f concave down? (c) Sketch the graph of f.
  • Find the derivatives of the functions: (a) $3x^{e}+e^{π}$ (b) $7\ln x+(1/x)-\ln 2$
  • Find antiderivatives of the functions: (a) $2\sqrt{x}+3$ (b) $5e^{x}+17x$
  • Suppose that F is an antiderivative of a differentiable function $f$. If F is increasing on $[a,b]$, what is true about $f$?
  • Evaluate $∫x\cos (1-x²)dx$
  • A ladder, $12$ feet long, is leaning against a wall. If the foot of the ladder slides away from the wall along level ground, what is the rate of change of the top of the ladder with respect to the distance of the foot of the ladder from the wall when the foot is 6 ft from the wall?
  • Is infinity a limit?
  • Is infinity a number?
