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)

I don’t know what the problem is
Answer:
Option 4 is the correct answer
Step-by-step explanation:
4. Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
1) A
time (week) 1 2 4 8 10
time (days) 7 14 28 56 70
B
X= days ( depended )
Y= weeks ( independed)
you should find the constant: Y= x/1 ( well in fact i dont remember)
you'll ask. why? well, days depends of the weeks that are
2)
oxygen atoms 2 5 17 120
hdrogen atoms 4 10 34 480
y=x/4
a little problem: i didnt remember the order of the X and Y, but i think is ok
Answer:
The solution is: v =
Step-by-step explanation:
Given equation is:
The given equation is a linear equation in one variable. The solution requires isolating v on one side of the equation. Simple equality properties can be used to solve the equation.
So,
Multiplying both sides of equation with 5
dividing both sides by 4
Adding 7 on both sides
Hence,
The solution is: v =
