slope of y=x^2+5x,x=4

slope

y = x^{2} + 5 x, x = 4

13

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 = 4 : 13

13

\frac{\partial}{\partial x} (7 + x^{2} + y^{2})

f (x) = x + \frac{9}{x}, (9, 10)

\int cos^{3} (t) - sin^{2} (t) cos (t) d t

y = x^{2} - 5 x - 6

f (x) = \frac{( x + 9 )}{x ^{2} - 7 x + 1}
