Integrate f′(x): To find f(1), we need to integrate the derivative f′(x) to get the original function f(x). The derivative f′(x) is given as 6x5+7. Integrate f′(x) with respect to x to find f(x). ∫(6x5+7)dx=∫6x5dx+∫7dx=(66)x6+7x+C=x6+7x+C, where f(1)0 is the constant of integration.
Find Constant C: We know that f(−2)=30. We can use this information to find the constant C.Substitute x=−2 and f(x)=30 into the equation f(x)=x6+7x+C.30=(−2)6+7(−2)+C30=64−14+C30=50+CC=30−50C=−20
Write Complete Function: Now that we have the constant C, we can write the complete function f(x).f(x)=x6+7x−20
Substitute x=1: To find f(1), substitute x=1 into the function f(x). f(1)=(1)6+7(1)−20 f(1)=1+7−20 f(1)=8−20 f(1)=−12
