Question

if y = f ( x ) = 7 × e× then find the derivative of y​

Answer 1

Step-by-step explanation:

Correct option is B)

Given, y=x−x

2

On differentiating w.r.t. x, we get

dx

dy

=1−2x

Now,

d(x

2

)

d(y

2

)

=

d(x

2

)

dx

d(y

2

)

d(x)

=

2x

2y

dx

dy

=2y

2x

(1−2x)

=

2x

2(x−x

2

)(1−2x)

=(1−x)(1−2x)

=1−3x+2x

2

=2x

2

−3x+1.
