Step-by-step explanation:

h = 1/2gt^2

multiply both sides by 2 to get rid of the 1/2

2h = gt^2

then divide both sides by g to get rid of g

2h/g = t^2

finally put both sides under the square root to get rid of ^2

the square root of 2h/g = t

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
