Answer:
Range = {5, 7, 9}
Step-by-step explanation:
<em>Range is the set of values that are the results of respective values of x when placed in the function f(x).</em>
f(3) = 2 × 3 - 1
f(3) = 6 - 1
f(3) = 5
f(4) = 2 × 4- 1
f(4) = 8 - 1
f(4) = 7
f(5) = 2× 5 - 1
f(5) = 10 - 1
f(5) = 9
Therefore, the range is the set of all these values :-
<u>Range = {5, 7, 9}</u>
Hello,
The largest possible number you can make is 986, because as you can see 9 is the highest number 8 is second highest and 6 is the least. Thats how the answer is 986

The value of y when x=8 and z = 1/4 is 1 based on the joint variation
<h3>How to determine the value of y?</h3>
The variation is given as
A joint variation
Such that y varies jointly as x and z
This means that
y = kxz
Where k is the constant of variation
From the question, we have
y=15 when x=5 and z=6
This means that
15 = k * 5 * 6
So, we have
15 = 30k
Evaluate
k = 0.5
Substitute k = 0.5 in y = kxz
y = 0.5xz
When x=8 and z = 1/4, we have
y = 0.5 * 8 * 1/4
Evaluate
y = 1
Hence, the value of y is 1
