Find Derivative of G(x): First, we need to find the derivative of G(x), which is g(x).g(x)=G′(x)=dxd[(x+3)2]Using the power rule, the derivative of (x+3)2 is 2∗(x+3).So, g(x)=2∗(x+3)
Calculate Integral of g(x): Now, we need to calculate the integral of g(x) from −1 to 7. ∫−172⋅(x+3)dx This is a simple polynomial integration problem. Integrate 2⋅(x+3) with respect to x. The antiderivative of 2⋅(x+3) is 2⋅(21)⋅x2+2⋅3⋅x, which simplifies to x2+6x. So, g(x)0
Evaluate Antiderivative: Evaluate the antiderivative from −1 to 7.Plug in the upper limit: (7)2+6∗(7)=49+42=91Plug in the lower limit: (−1)2+6∗(−1)=1−6=−5Now subtract the lower limit result from the upper limit result.91−(−5)=91+5=96
