limit as x approaches 9 of 8x+|x-9|

x \to 9 lim (8 x + ∣ x - 9 ∣)

72

Solution steps

x \to 9 lim (8 x + ∣ x - 9 ∣)

Plug in the value

x = 9

= 8 \cdot 9 + ∣ 9 - 9 ∣

Simplify

8 \cdot 9 + ∣ 9 - 9 ∣ : 72

= 72

\frac{\partial}{\partial y} (2 x y^{3} - 3)

4 x^{\frac{5}{4}} + 8 x^{\frac{3}{2}} + 3 x

y^{^{'}} = \frac{( y - y ^{2} )}{x}

\frac{1 + x}{1 - x} - 1

f (x) = sec (x^{2})
