Finish the steps below to write a quadratic function for the parabola shown. 4 Use the vertex form, f(x) = a(x - h)2 + k, and substitute in the values for h and ke. f(x) = a(x – 5)2 + 3 2. Use another point and substitute in values for x and f(x). Solve for a. 5 = a(6 – 5)2 + 3 3. Write the function, using the values for h, k, and a. The function is f(x) = Tx - 12​

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Do,h = (7, 9) (14, 18) the scale factor is
