Answer:
Option B.(4,-4)
Step-by-step explanation:
we know that
1) An angle 45 degrees means that the absolute value of the x-coordinate of the point on the terminal side is equal to the absolute value of the y-coordinate of the point on the terminal side
2) An angle of -45 degrees lies on the IV Quadrant
That means------> The x-coordinate is positive and the y-coordinate is negative
therefore
The point on the terminal sides of -45 degrees is the point (4,-4)

Step-by-step explanation:
Answer:
(fog)(a) = a³ - 3a² + 4a - 2
= (a - 1)×(a² - 2a + 2)
Step-by-step explanation:
<u><em>Given</em></u> :
g(a) = a -1
f(a)= a³ +a
…………………………
(fog)(a) = f(g(a)))
= g(a)³ + g(a)
= (a - 1)³ + (a - 1)
= (a³ - 3a² + 3a - 1) + (a - 1)
= a³ - 3a² + 3a - 1 + a - 1
= a³ - 3a² + 3a + a - 1 - 1
= a³ - 3a² + 4a - 2
<u><em>Second method</em></u> :
(fog)(a) = f(g(a)))
= f(a - 1)
= (a - 1)³ + (a - 1)
= (a - 1)×[(a - 1)² + 1]
= (a - 1)×[a² - 2a + 1 + 1]
= (a - 1)×(a² - 2a + 2)
