Explain why this function, is not continuous at x=0

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
