CAN SOMEONE PLZ HELP ME, I NEED IT ASAP, AND I WOULD LIKE IT IF U COULD EXPLAIN YOUR ANSWER Functions f(x) and g(x) are shown below:

f(x) = x2
g(x) = x2 + 8x + 16

In which direction and by how many units should f(x) be shifted to obtain g(x)? (1 point)

Left by 4 units
Right by 4 units
Left by 8 units

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

The square root of 9x plus 7 plus the square rot of 2x equall to 7
