Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs
well the period for this function will then be </span>

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally
It’s around 450 euros right now - to figure this out you multiply the number of pounds by the current exchange rate ( which you can look up)
Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/( -3 - -3)
= ( -4-4)/( -3+3)
= -8/0
When we divide by zero, the answer is undefined so the slope is undefined
