slope of y=x^2+5x,x=8

slope

y = x^{2} + 5 x, x = 8

21

Solution steps

y = x^{2} + 5 x

In order to find the slope of the function, take the derivative of

x^{2} + 5 x

\frac{d}{d x} (x^{2} + 5 x) = 2 x + 5

2 x + 5

Find the value of

2 x + 5

for

x = 8 : 21

21

\int (x^{2} - 2 x + 3) d x

\int \frac{3 x ^{3}}{x ^{2} + 1} d x

n = 0 \sum \infty \frac{1}{n}

\frac{\partial}{\partial x} (x^{0.7} y^{0.3})

\int_{0}^{1} 3 e^{- 2 x} d x
