.72
.725 would be less because it has more behind the decimal.
.72 would be more because there are only 2 numbers behind the decimal
Y= -1x + -1 is the answer
They are opposites. since |-3| has the lines around it, this represents absolute value, which is not positive or negative but how far away the value is from 0. the plain -3 remains the same. |-3| is 3, because it is 3 units away from 0 on the number line.
Let me see the bubble chart
F(x)=x^2 - 4x - 4x +16-16-9
=x(x - 4) -4(x - 4) - 25
= (x-4)(x-4) -25
f(x)=(x-4)^2 - 25
the vertex is (4, -25)
the vertex occur at
x = - b/2a and y = (4ac - b^2)/4a
x= - - 8/(2*1)=4
y=[4*1*(-9) - (-8)^2]/(4*1)
= (-36-64)/4 = - 100/4 = - 25
