Shifting to left mean adding the number from each occurrence of x from the given function.
So, shifting x³ , 3 units to left will result in:
f(x) = (x + 3)³
Shifting down means subtracting the number from the function value.
So, shifting 2 units down will result in:
f(x) = (x + 3)³ - 2
Therefore, option A is the correct graph
So P(-0.7537 < z < 1.3190) = 0.9063 - 0.2254 = 0.6809
Number 3 is 100 number 4 is 112
