# limit of a constant function

There is one special case where a limit of a linear function can have its limit at infinity taken: y = 0x + b. Compute $$\lim\limits_{x \to -2} \left ( 3x^{2}+5x-9 \right )$$. ... Now the limit can be computed. ) %PDF-1.5 %���� If you are going to try these problems before looking at the solutions, you can avoid common mistakes by giving careful consideration to the form during the … So we just need to prove that → =. 1). 5.
