The given function is

Differentiating

Again differentiating

Substituting the values of y '' and y in

We will get

Answer:
A
Step-by-step explanation:
The first 1 in 1 contains two 1's , both formed by adding the two numbers above them to the left and the right in this case 1 and 0(all numbers outside the triangle are 0's).Do the same to create the second row :0+1 =1;1+0=1;1+1=2;1+0=1;And the third row you put:0+1 =1;1+2=3;2+1 =3;1+0=1
3+ x/2 = 10 .......> Given
x/2 = 7 ...............>Subtraction property of equality
x = 14 ..........> Multiplication property of equality
