if f(x) = -2x + 4x, complete the square and determine the minimum or maximum value of the function.
f(x) = -2(x - 1)4 + 2 and f(x) has a maximum value f(1) = 2.
f(x) = -2(x - 1)2 + 2 and f(x) has a minimum value f(1) = 2.
f(x) = -2(x - 1)2 - 1 and f(x) has a maximum value f(1) = -1.
d)
f(x) = -2(x - 1)2 - 1 and f(x) has a minimum value f(1) = -1.

hi there!

the answer will be d: 2

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
