Does anyone know the minim value of the function f(x) =2x^2 -4x -6?. I’m online due to my quarantine and am looking for extra he
navik [9.2K]

Answer:

f(x) = - 8

Explanation:

The given function is

f(x) =2x^2 -4x -6

The first step is to find the derivative of the function. Recall, if

y = ax^b

y' = abx^(b - 1)

Thus,

f'(x) = 4x - 4

We would equate f'(x) to zero and solve for x. We have

4x - 4 = 0

4x = 4

x = 4/4

x = 1

We would substitute x = 1 into the original function and solve for f(x) or y. It becomes

f(1) =2(1)^2 -4(1) - 6 = 2 - 4 - 6

f(1) = - 8

Thus, the minimum value is f(x) = - 8

Answer:

Answer is option a) 6x m.

Step-by-step explanation:

given \: \:  diagonal \: \:  d1 = x + 2 \:  \: m \\  area \:  \:  = 3x {}^{2}  + 6x \:  \:  \: m \\ to \: find \: d2 \:  = answer \\ area \: of \: rhombus \:  =  \frac{1}{2}  \times d1 \times d2 \\ 3x {}^{2}  + 6x \:  =  \frac{1}{2}  \times (x + 2)  \times d2 \\ 2( \frac{3x {}^{2} + 6x }{x + 2} ) = d 2\\  \frac{6x {}^{2} + 12x}{x + 2}  = d2 \\  \\ solving \: the \: above \: equation \: we \: get \:  \\ d2 = 6x \:  \: m
