Answer:

f(- 2) = - 1

Step-by-step explanation:

f(- 2) = 3 - (- 2)² = 3 - 4 = - 1

tamaranim1 [39]

The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. Mode is the number which appears most often in a set of numbers.

Hope this helps you :)

Anyone pzzz answer this giving brainlist and 50 points for correct answer
Nuetrik [128]

Answer:

see below

Step-by-step explanation:

12x+24x+18 = 36x+24-6

Combine like terms

36x+18 = 36x+18

Subtract 36x from each side

36x+18-36x = 36x+18-36x

18 = 18

This is always true, so the equation is true for all values of x
