Option C

{(0, 1), (1, 5), (2, 9)} represents possible inputs and outputs of the function

Solution:

Given function is:

y -1 = 4x

y = 4x + 1

To find the set which represents possible inputs and outputs of the function. Let's check all the options

Let us use the ordered pair (1, 4)

Substitute (x, y) = (1, 4) in given function

4 = 4(1) + 1

4 = 4 + 1

Thus this set is not the required set

Let us use the ordered pair (4, 1)

Substitute (x, y) = (4, 1) in given function

1 = 4(4) + 1

1 = 16 + 1

Thus this set is not the required set

Let us use the ordered pair (0, 1)

Substitute (x, y) = (0, 1) in given function

1 = 4(0) + 1

1 = 1

Thus this set is the required set represents possible inputs and outputs of the function.

Let us use the ordered pair (1, 0)

Substitute (x, y) = (1, 0) in given function

0 = 4(1) + 1

0 = 4 + 1

Thus this set is not the required set

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
