Consider the function y = cos(x). Which change would increase the period by a factor of 3? Multiply cos(x) by One-third Multiply cos(x) by 3. Multiply x by One-third Multiply x by 3.

its multiply x by 1/3

Step-by-step explanation:

C on edg

Step-by-step explanation:

multiply x by (1/3)

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
