Which quadratic function has vertex (-1,4) and passes through (4,19)

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by:

Where (h,k) is the vertex.

It was given in the question that the vertex of the parabola is (-1,4).

When we substitute the vertex into the formula we get:

The parabola also passes through (4,19) hence it must satisfy its equation.

We divide both sides by 25 to get:

Hence the quadratic function is:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
