Find the maximum/minimum value of y = x2 - x + 1/4. At what value of x it occurs?

f(x) has a minimum value is zero at  

Step-by-step explanation:

Explanation:-

step(i):-

Given function y =f(x)=  x² - x + 1/4 ....(i)

Differentiating equation (i) with respective to 'x', we get

 ...(ii)

Equating Zero   2 x - 1 = 0

Step(ii):-

Again differentiating with respective to 'x', we get

f(x) has a minimum value at  

Step(iii):-

y =f(x) =  x² - x + 1/4

Put  

f(x) has a minimum value is zero at  

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
