limit as x approaches 2 of-x^2+bx-1

x \to 2 lim (- x^{2} + b x - 1)

2 b - 5

Solution steps

x \to 2 lim (- x^{2} + b x - 1)

Plug in the value

x = 2

= - 2^{2} + b \cdot 2 - 1

Simplify

= 2 b - 5

\frac{d}{d x} (4 x^{2} - 11 x - \frac{5}{x ^{3}})

x \to 0 lim (cos (4 x))

(x^{2} + 1) y^{^{'}} + 4 x (y - 1) = 0

49 - x^{2}

f (x) = x^{3} - 3 x^{2} + 4 x + 5, x = 3

What is the limit as x approaches 2 of-x^2+bx-1 ?
The limit as x approaches 2 of-x^2+bx-1 is 2b-5
