Given the point (-7, 9), what would the coordinates be after that point was translated 4 units up? ( _ , _ )

Just add 4 to the y-coordinate, 9:

(-7,9) => (-7,9+4) => (-7,13)

1/4 because there is 4 grades.

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
