Which function matches the table? Helppp

C. f(x) = 2x² - 1.

Step-by-step explanation:

Using any of the given pair, slot in the values of the pair into each function given to find out if it would satisfy the equation.

Let's use (1, 1).

Option A: f(x) = 2x - 1:

Substitute x = 1 and f(x) = 1 into the function

1 = 2(1) - 1

1 = 2 - 1

1 = 1 (this is true).

However, let's try this using another given pair, (2, 7) to confirm if the function matches the table.

Substitute x = 2 and f(x) = 7 into f(x) = 2x - 1

7 = 2(2) - 1

7 = 4 - 1

7 = 3 (this is not true). Therefore the function doesn't match.

✔️Let's check option C: f(x) = 2x² - 1.

Substitute x = 1, and f(x) = 1 into the function

1 = 2(1)² - 1

1 = 2 - 1

1 = 1 (true)

Try another pair, say (2, 7):

Substitute x = 2 and f(x) = 7 into f(x) = 2x² - 1

7 = 2(2)² - 1

7 = 2*4 - 1

7 = 8 - 1

7 = 7 (true).

Therefore, C. is the correct answer.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
