limit as x approaches 4 of 5x^2-2x

x \to 4 lim (5 x^{2} - 2 x)

72

Solution steps

x \to 4 lim (5 x^{2} - 2 x)

Plug in the value

x = 4

= 5 \cdot 4^{2} - 2 \cdot 4

Simplify

= 72

\frac{4 + t}{t e ^{t}}

\int \frac{1}{t ^{3} t ^{2} - 1} d t

\int_{0}^{1} x 1 + 8 x^{2} d x

\int (x^{2} - 4 x + 3) d x

\int sin^{4} (2 x) cos^{3} (2 x) d x
