Flip over vertical axis-Apex

Your question is a bit odd. cos(-x)=cos(x) and so, the function will be the same as just y=cos(x)-4. No change will be appreciable. You can test it using https://www.desmos.com/calculator

and copying your function. In general, x->-x tests a symmetry around the vertical axis, so d) if any. No shifts here added by changing x by (-x)

Answer:

1/8x + 1/8x

Step-by-step explanation:

We are looking for 1/4x

1/8x + 1/8x = 2/8x which reduces to 1/4x

1/8x + 1/8 Cannot be added as they are not like terms

1/8 + 1/8 = 2/8 which reduces to 1/4 but doesn't have an x

1/2x + 1/2x = 2/2x which reduces to x

Therefore 1/8x + 1/8x is equivalent
