Plz help me with this

1 answer:

3 0

Answer:

It's the first option.

Step-by-step explanation:

y = cos x transformed to cos (x - π/2) moves the graph π/2 units to the right.

Multiplying by 3 to give 3 cos(x - π/2) stretches the graph 3 units parallel to the y-axis and adding 3 to this moves the graph up 3 units.

So the required equation is y = 3(cos x - π/2) + 3.

Step-by-step explanation:

y intercept: x=0 y = (-1/18) * 3 * (-3) * (-4) = - 2

y = -1/18 * (x³ - 4x² - 9x +36) ... leading coefficient: (-1/18 x³) -1/18

highest degree:( x³) 3
