1. If p(x) = 3x + 4x² - 5x +8, find p(-2).

levacccp [35]

Step-by-step explanation:

$\small{\underline{\tt{\red{Given}}}}$

$\rightarrow$ p(x) = -2

$\small{\underline{\tt{\green{solution}}}}$

$\rightarrow$ $p(x) = 3x + {4x }^{2} - 5x + 8$

$\rightarrow$ $p( - 2) = 3( - 2) + 4( { - 2}^{2} ) - 5( - 2) + 8$

$\rightarrow$ $p( - 2) = - 6 + 16 + 10 + 8$

$\rightarrow$ $p( - 2) = 10 + 18$

$\rightarrow$ $p( - 2) = 28$

$\small\boxed{p(-2) = 28 }$

Hope it helps

If f(x) = [xl-5, what is f(8.6)?

Fynjy0 [20]

Answer:

3 or 4, depending on the intended meaning of [x]

Step-by-step explanation:

Perhaps you mean ...

$\displaystyle f(x)= \lfloor x\rfloor -5\\\\f(8.6)=\lfloor 8.6\rfloor-5=8-5=3$

On the other hand, perhaps you mean ...

$\displaystyle f(x)=\lceil x\rceil -5\\\\f(8.6)=\lceil 8.6\rceil-5=9-5=4$
