Question

Find the function whose first difference is
9x^2+11x+5

Answer 1

Answer:

we can find it by the help of its integeration

Explanation:

Answer 2

Answer:

The function is $3x^3+\frac{11}2*x^2+5x+c$

Explanation:

On integrating the function with respect to dx we get the function whose first difference is $9x^2+11x+5$

On integrating we get
$\int {9x^2+11x+5} \, dx \\\\9x^3*\frac13 + 11x^2*\frac12 + 5x + c\\\\3x^3+\frac{11}2*x^2+5x+c$
where c is a constant.

So the function is $3x^3+\frac{11}2*x^2+5x+c$
