Answer:
(B) A function is a relation in which each value of the input variable is
paired with at least one value of the output variable.
(D) The vertical line test may be used to determine whether a function
is one-to-one.
Both of these are incorrect/false statements
(I used these in my test on Apex and got both correct)
This means that if the question was reversed and asking about the statements are true, the answers would be:
(A) A sequence is a function whose domain is the set of natural
numbers.
(C) The horizontal line test may be used to determine whether a
function is one-to-one.
Answer:
3/2
Step-by-step explanation:
The composition of transformations has you dilate the line by a factor of 1/2, then by a factor of 3. Then the line is rotated about the origin.
The scale factor of the result will be the product of the dilation factors:
(3)(1/2) = 3/2
The scale factor of the transformation is 3/2.
Answer:
7-4+6=7 + 2
Step-by-step explanation:
(0,5)(3,-1)
slope = (-1 - 5) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(use either of ur points...(0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = -2(0) + b
5 = b
so ur line is : y = -2x + 5
Answer:
<em>-9.7 + 18.6</em>
Step-by-step explanation:
Given the expression:
-9.7 - (-18,6)
The additive inverse of -18.6 is 18.6
The product of teo negative sign will also give a positive sign, hence:
-9.7 - (-18,6) = -9.7 + 18,6
-9.7 + 18,6 = 18.6 - 9.7
18.6 - 9.7 = 8.9
<em>Hence the expression can also be written as -9.7 + 18.6 with 8.9 being the solution</em>
