Help me guys :(
i need your help, please.!!!?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

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

Which number line correctly shows 0.8 + 0.3?
