What is the rounded 18998 to the nearest ten thousand?

It rounded to the nearest ten thousands is 20,000

because of the saying 5 and above give it a shove and 4 and below let it go

and since 8 is greater than 5 it is rounded up

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

thus, the first answer choice, y = sec x, is the correct one
