For Problems 1 and 2, directly use the definition on pg. 83 3.1 CONTINUITYOF A FUNCTION AT A POINT2. Define f: [-4, 0]→ R by f(x) =1. Define f: R→→ R by f(x) = 3x² - 2x + 1. Show that f is continuous at 2.2x² - 18x +3continuous at -3.for x-3 and f(-3) = -12. Show that f is DEFINITION Suppose ECR and f: E→ R. If xo E E, then f is continuousat xo iff for each e > 0, there is a 8 >0 such that ifIx-xo <8, x E E,then|f(x) = f(xo)| < €.If f is continuous at x for every x E E, then we say f is continuous.

Given:The function is defined as .Objective:To show that is continuous at 2.Concept:A function…
