more parabola stuff :DDD
I was given a parabola (not required a drawing), and I have calculated the formula - (x+2)(x-1), I was then told that it moves 3 space to the right and 5 up and to calculate the new Y intercept.

This is what I did
I calculated the vertex -2 and 1= 3/2 = 1.5
-2+1.5=.5 from their i did .5 into -(x+2)(x+1) which game me -(2.5x.5)= -1.25 now I knw the vertex is -.5 x and 1.25y from their i did -.5+3=2.5 and then 1.25+5 = x2.5 and y 6.25 then I made the vertex formula -(x -2.25)^2 + 6.25 and then substituted x=0 which game me 0, but the answer is 1? any guides on where I went wrong?

To move the graph of a function \$\displaystyle y=f(x)\$ 3 units to the right and 5 units up, you could use \$\displaystyle y=f(x-3)+5\$.
