Using numbers, variables and symbols, write an expression that describes the following the sum of 12 and three times a number , n

12=3n

Step-by-step explanation:

Starting with "the sum 12" that means it equals 12 so, 12 = Something.

And three times a number, N would look like this ; 3n.

So the sum of 12- 12 = , three times a number n

12=3n

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
