USING STRUCTURE In Exercises 27-30, describe the transformation of the graph of the parent quadratic
function. Then identify the vertex.
27. f(x) = 3(x + 2)2 + 1
28. f(x) = -4(x + 1)2 - 5
29. f(x) = -2x2 + 5
30. f(x) = (x - 1)2

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:
