Question

if p(x)=5x+3find p(o),p(1),and p,(-2)​

Answer 1

Answer:

p(x)=5x+3

p (0)=5×0+3

p (0)=3

p(1)=5×1+3

p (1)=8

p(-2)=5×-2+3

p (-2)=-10+3

p (-2)=-7

Answer 2

$\large\underline{\sf{Given- }}$

$\rm :\longmapsto\:p(x) = 5x + 3$

$\large\underline{\sf{To\:Find - }}$

$\rm :\longmapsto\:p(0)$

$\rm :\longmapsto\:p(1)$

$\rm :\longmapsto\:p( - 2)$

$\large\underline{\sf{Solution-}}$

Given that

$\rm :\longmapsto\:p(x) = 5x + 3 - - - (1)$

To find p(0)

Substituting 'x = 0' in equation (1), we get

$\rm :\longmapsto\:p(0) = 5 \times 0 + 3$

$\rm :\longmapsto\:p(0) = 0 + 3$

$\rm :\longmapsto\: \boxed{ \bf{p(0) = 3}}$

To find p(1)

Substituting 'x = 1' in equation (1), we get

$\rm :\longmapsto\:p(1) = 5 \times 1 + 3$

$\rm :\longmapsto\:p(1) = 5 + 3$

$\rm :\longmapsto\: \boxed{ \bf{p(1) = 8}}$

To find p(- 2)

Substituting 'x = - 2' in equation (1), we get

$\rm :\longmapsto\:p( - 2) = 5 \times ( - 2) + 3$

$\rm :\longmapsto\:p( - 2) = - 10 + 3$

$\rm :\longmapsto\: \boxed{ \bf{p( - 2) = - 7}}$
