Answer

f(x)=43x3+52x25x+3

Steps

Step 1 :Given the derivative function f(x)=4x2+5x5 and the initial condition f(0)=3.

Step 2 :Integrate the derivative function to find f(x): f(x)=f(x)dx=(4x2+5x5)dx=43x3+52x25x+C.

Step 3 :Substitute the initial condition f(0)=3 into the function to find the constant C: 3=43(0)3+52(0)25(0)+C, so C=3.

Step 4 :Substitute C=3 back into the function to get the final answer: f(x)=43x3+52x25x+3.

Step 5 :f(x)=43x3+52x25x+3
