Answer:
( y + 9 ) = -10( x - 1 )
Step-by-step explanation:
First we calculate the slope
Then we choose a point it could be (1,-9) or (-10,101), I choose (1,-9), the slope point form is (y-y1)=m(x-x1)
( y - (-9) ) = -10( x - 1 )
( y + 9 ) = -10( x - 1 )
it could be also...
( y - 101 )= -10( x- (-10) )
( y - 101 ) = -10( x + 10 )
Hi there!
We can use "Completing the Square" to solve:
f(x) = x² - x + 2
Group the variables. The "x" term's coefficient will be divided by two and squared for the third part of the trinomial. Remember to subtract by the third term:
f(x) = x² - x + (1/2)² + 2 - (1/2)²
Group:
f(x) = (x - 1/2)² + 2 - 1/4
Rewrite:
f(x) = (x - 1/2)² - 7/4
Thus, the first answer is correct.
