The range of the function f(x) = 2x² -7 with domain: x = {-4, -2, 0, 3} is y = (25, 1, -7, 11). Option D is the correct answer.
The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x).
A function's range is the collection of values it can take as input. After we substitute an x value, this set of values is what the function outputs. The y values are those.
In light of the query
x VS F(x) = 2x² -7
-4 F(4) = 
= 25
-2 F(-2) = 
= 1
0 F(0) = 
= -7
3 F(3) = 
= 11
∴ Option D, y = (25, 1, -7, 11)

The proportion would be -
12 / 150 = x / 225.
That is, 12 per 150, x amount per 225
To solve this proportion, you can cross multiply (multiply the values diagonally) -
12 / 150 = x /225
150x = 12(225)
150x = 2700
x = 18
18 vials are required to treat 225 people.
Hope this helps! (:
Answer:
y=7/9x-2
Step-by-step explanation:
This is the formula to follow when doing these equations
y=slopex (-/+) y-intercept
if it a negative it a - intercept if it a positive intercept if adding.

Step-by-step explanation:
Using conditional probability, it is found that P(X⏐Y) = 0.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, we have that X and Y are mutually exclusive events, hence 
, hence:
