If the original function f(x) = 2x2 - 1 is shifted to the left 3 units to make the function g(x), which expression would represent g(x)? (1)2(x-3)^2-1 (3)2x^2+2 (2)2(x+3)^2-1 (4)2x^2-4
To shift the f(x) function 3 units to the left, the xy axis must move 3 units to the right. This effectively means each x input is 3 units larger than before. That's why we replace every x with x+3.
