Answer:

7/9

Step-by-step explanation:

Evaluate the expression at x=8-. You can see from the graph that p(8-) = 3.

$\displaystyle \lim_{x\to8^-}{\frac{3p(x)-2x}{15-3x}}=\frac{3(3)-2(8)}{15-3(8)}=\frac{-7}{-9}=\boxed{\frac{7}{9}}$

1) Answer: $-\frac{3}{2}$

Step-by-step explanation:

f(x) = 6x⁻¹

f'(x) = -6x⁻²

= $\frac{-6}{x^{2}}$

f'(-2) = $\frac{-6}{(-2)^{2}}$

= $-\frac{6}{4}$

= $-\frac{3}{2}$

*****************************************************

2) Answer: $\frac{1}{4}$

Step-by-step explanation:

f(x) = -9x⁻¹

f'(x) = 9x⁻²

= $\frac{9}{x^{2}}$

f'(6) = $\frac{9}{(6)^{2}}$

= $\frac{9}{36}$

= $\frac{1}{4}$
