Question

who do I find a value of A that makes f(x) continues everywhere where,

Answer 1

if f(x) is continuous at a point , that means the curve thingy is not incomplete.tell the exact question for a better answer . At that point the left hand limit is equal to the right hand limit and is equal to the y value of that x value .

Answer 2

use \[5x ^{2} if \le 2 \] and 2x+A if x\[x \ge 2\]
