(2x + 4) ( 2x + 3) = 4x² + 6x + 8x + 12 = 4x² +14x + 12
(4x + 5) (x + 1) = 4x² + 4x + 5x + 5 = 4x² + 9x + 5
(2x + 1) (2x + 5) = 4x² + 10x + 2x + 5 = 4x² + 12x + 5
Question one is (2x + 1) (2x + 5)

Which of these tables could represents quadratic function?
myrzilka [38]

When values of a quadratic function are listed in a table with x-values having a constant difference, the y-vlaues will have a constant (non-zero) second-difference.

Here, we can list first and second differences for the values in the given tables to identify the quadratic function.

Table 1.

  • 1st differences: 3, 3, 3, 3
  • 2nd differences: 0, 0, 0, 0 . . . . this is a linear function

Table 2.

  • 1st differences: -6, -2, 2, 6
  • 2nd differences: 4, 4, 4 . . . . this is a quadratic function

Table 3.

  • 1st differences: 5, -8, -3, -3
  • 2nd differences: -13, 5, 0 . . . . can be described by a 4th degree polynomial

Table 4.

  • 1st differences: 3, 0, -3, -3
  • 2nd differences: -3, -3, 0 . . . . can be described by a 4th degree polynomial

___

The appropriate choice is Table 2.

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?
Alla [95]
The graph has been moved 3 units downward, making the range change. The range of f(x) is [-5,5], while the range of g(x) is [-8,2]. The picture is of both functions. f(x) is blue, g(x) is red.
