Question

A. P(x)=5x-π,x=4/5
B. p(x)=lx+m,x=-m/l

Answer 1

Answer:

$p(\frac{4}{5})=4-\pi$

$p(\frac{-m}{l})=0$

Step-by-step explanation:

$i) If \: x = \frac{4}{5}\: then\\the \: value \: of \:p(x)=5x-\pi$

$p(\frac{4}{5})=5\times \frac{4}{5}-\pi\\=4-\pi$

$ii) If \: x = \frac{-m}{l}\: then\\the \: value \: of \:p(x)=lx+m$

$p(\frac{-m}{l})=l\times \frac{-m}{l}+m\\=-m+m\\=0$
