The parabola y=x^2 is shifted up by 7 units and to the left by 1 unit.

Step-by-step explanation:

f (x) + n - shift up by n units

f (x) - n - shift down by n units

f (x - n) - shift to the right by n units

f (x + n) - shift to the left by n units

We have y = x² → f(x) = x². Shifted up by 7 units and to the left by 1 unit:

use (a + b)² = a² + 2ab + b²

Step-by-step explanation:

I did it on Khan and it was right.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
