A good app that would help you with math is photomath
Answer:
(-4,22)
Step-by-step explanation:
is the right answer
Horizontal Shrink: y = cos 2x or if the coefficient of x is greater than 1
Vertical Stretch: y = 2 cos x or if the coefficient if cos x is greater than 1
Horizontal Stretch: y = cos (1/2) x or if the coefficient of x is less than 1
Vertical Shrink: y = (1/2) cos x or the coefficient of cos x is less than 1
The base value is 1 since it is the original coefficient of x and cos x. The values would adjust depending on the original coefficients.
The last one is correct because 60+35+35+35=165
55+55+55=165
