limit as x approaches 3 of 5x^2-7x-3

x \to 3 lim (5 x^{2} - 7 x - 3)

21

Solution steps

x \to 3 lim (5 x^{2} - 7 x - 3)

Plug in the value

x = 3

= 5 \cdot 3^{2} - 7 \cdot 3 - 3

Simplify

5 \cdot 3^{2} - 7 \cdot 3 - 3 : 21

= 21

(10 x^{2} - 20 x + 20) e^{- 6 x}

\int \frac{( sin ^{3} ( x ) )}{cos ( x )} d x

\frac{d}{d x} (4 x^{3} + 3 x)

\int_{- 1}^{7} (2 x + 7) - (x^{2} - 4 x) d x

\int \frac{1}{- csc ( y )} d y
