Question

explain how to find the maximum value for each function and determine which function has the largest maximum y-value.

Answer 1

@UnkleRhaukus

Answer 2

The function is \[g(x) = 2\cos(2x-\pi)+4\]

This will have maximum values when the cosine term is at maximums

Answer 3

f(x) = −4(x − 6)^2 + 3

Answer 4

do you know what the largest value of \(\cos\theta\), can ever be? (for all possible angles \(\theta\) )

Answer 5

no

Answer 6

remember that cosine is the ratio of the adjacent side in a right angled triangle, to its hypotenuse,
(note that the hypotenuse is always the largest side)

Answer 7

ok ok , i get that
