limit as x approaches-1 of 4x^2-8x+3

x \to - 1 lim (4 x^{2} - 8 x + 3)

15

Solution steps

x \to - 1 lim (4 x^{2} - 8 x + 3)

Plug in the value

x = - 1

= 4 (- 1)^{2} - 8 (- 1) + 3

Simplify

4 (- 1)^{2} - 8 (- 1) + 3 : 15

= 15

\int e^{- x} cos (3 x) d x

7 t \cdot \frac{d y}{d t} - y = t

x \to 4 + lim (e^{4 - x})

f (x) = arcsin (6 x)

\frac{d}{d x} (81 - 16 x^{2})
