limit as x approaches 4 of 4x+2x^2

x \to 4 lim (4 x + 2 x^{2})

48

Solution steps

x \to 4 lim (4 x + 2 x^{2})

Plug in the value

x = 4

= 4 \cdot 4 + 2 \cdot 4^{2}

Simplify

= 48

\int cos^{5} (9 - x) sin (9 - x) d x

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

\int 3 cot^{5} (θ) sin^{4} (θ) d θ

x^{2} - 2 x + 1
