Nonamiya [84]

Answer:

y = 13x + 86

Step-by-step explanation:

y−8 =13(x+6); distribute the 13

y - 8 = 13x + 78; now add 8 to both sides

Which graph represents the function y = cos(4x)?<br><br> Answer is graph B

VARVARA [1.3K]

Answer:

Step-by-step explanation:

Let the equation of the cosine function is,

y = Acos(Bx)

From the graph attached,

A = Amplitude = $\frac{1-(-1)}{2}$

= 1

B = $\frac{2\pi}{\text{Period}}$

B = $\frac{2\pi}{\frac{\pi}{2}-0}$

B = $\frac{4\pi}{\pi}$

B = 4

Therefore, equation of the cosine wave given in the graph will be,

y = 1.Cos(4x)

y = Cos(4x)
