can someone help me solve for maximum y-value. The equation is f(x)-x^2+6x+3

2. DXX101

2x+4 =4x -20 -2x -2x 4=2x-20 +20 +20 24=2x /2 /2 x= 12

how come it's not -12?

4. sabrena731

Im trying to find the maximun value of y.

5. sabrena731

Im confused.

6. DXX101

it is not -12 because it is a subtraction symbol not a negative symbol I hoe this helps.
