Answer:
0,-4 is the y-intercept and y2+x is the equation I think
Step-by-step explanation:
If there are 2 variables<span> and they are I(1) then u </span>can<span> apply enger and granger ... Recently I came across the 1st </span>difference<span> OLS model in a thesis
hope this helps!</span>
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
