Answer:
Yes
Step-by-step explanation:
Given
Required
Is f a function of A->B
f can be rewritten as
x --- y
a -- 6
b -- 4
c -- 6
The x column is regarded as the input while the y is the output
Notice that for every input, there is a corresponding output and no input points to multiple outputs.
i.e No value of x has more than 1 value of y
<em>Because of this singular reason; f is a function of A->B</em>
Answer:
.3636363636
Step-by-step explanation:
Because 2/3 x6/11 equals the answer
Top:
(-1/2 +1)(1/2 -1)(1+1)
= (1/2) (-1/2)(2)
= -1/2
so
-1/2 / 1/2)
= -1/2 x 2
= -1
answer is -1
