Answer:
Step-by-step explanation:
Parent function of the square root function has been given as,
f(x) =
If the graph of the given function is stretched vertically by the scale factor = g(x) =
If the graph is shifted 3 units to the left,
h(x) =
Since, the graph of the function passes through a point (-2, 2),
2 = k
Therefore, the function is .
Answer:
275
Step-by-step explanation:
Given that a survey of 391 children given at a local elementary school showed that 150 like chocolate ice cream, 225 like pistachio ice cream, and 116 do not like chocolate or pistachio ice cream.
Total = 391
cholocate ice cream =150
pistchio ice cream = 225
Neither -=116
If we partition universal set into disjoint sets exhaustive
we have A-B, B-A, AB, and (AUB)'
Total = 391
Let n(AB) i.e. likes both be x
Then we have n(A-B) = 150-x and n(B-A) = 225-x
Totalling
no of children who like atleast one kind of ice cream = n(U)-n(AUB)"
= 391-116
= 275
