Find two functions that this could be the derivative of:

y'=4x+7

I have one: y=2x^2 + 7x

I cant think of another one!!

add a constant.

Remember that you can add an arbitrary constant to any integral. The derivative will be the same.

To find another function whose derivative is y' = 4x + 7, you can take the integral of the given expression.

Integrating the equation y' = 4x + 7 with respect to x will yield the original function y, up to an arbitrary constant of integration.

Integrating 4x + 7 with respect to x, we get:

y = 2x^2 + 7x + C

where C is the constant of integration.

This is the same function you had mentioned: y = 2x^2 + 7x.

By adding a constant C, you can obtain various functions that satisfy the given derivative.

For example, if C = 1, then y = 2x^2 + 7x + 1 is another function whose derivative is y' = 4x + 7.

In general, you can choose any constant C and it will result in a different but valid function that has the same derivative.
