Answer:

D, y = cos(x -π/2)

Step-by-step explanation:

When the cosine function is shifted right by π/2 units, it looks like the sine function. That is what we have here. To shift f(x) to the right, replace x by x-(amount of shift). Here, this means the graph is described by ...

y = 2cos(x -π/2)

_____

The vertical scale factor is 2 on the graph and in all answer choices.

Find the product of (x^2+2x-3)(4x^2-5x+6)

Evgesh-ka [11]

Answer:

$x^{4}$ + 3x³ - 16x² + 27x - 18

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(4x² - 5x + 6) + 2x(4x² - 5x + 6) - 3(4x² - 5x + 6)

Distribute all 3 parenthesis

= 4 $x^{4}$ - 5x³ + 6x² + 8x³ - 10x² + 12x - 12x² + 15x - 18

Collecting like terms

= 4 $x^{4}$ + 3x³ - 16x² + 27x - 18
