limit as x approaches 2 of 2x^2+a/2 x-4

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

a + 4

Solution steps

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

Plug in the value

x = 2

= 2 \cdot 2^{2} + \frac{a}{2} \cdot 2 - 4

Simplify

2 \cdot 2^{2} + \frac{a}{2} \cdot 2 - 4 : a + 4

= a + 4

d er i v a t i v e (x^{2} - x + 2)^{3}

\int \frac{1 + e ^{- x}}{e ^{x}} d x

y^{^{'}} + y x^{3} = 4 x^{3}

x \to 0 lim (x^{2} + 9 - 3)
