Question

Find the value of q(t)=4t³-3t2-5t-4 at t= -2 2​

Answer 1

Step-by-step explanation:

.

Given, q(t)=4t³-3t²-5t-4

and, t=(-22)

Putting the value of 't',

q(-22)=4×(-22)³ - 3×(-22)² - 5×(-22) - 4

q(-22)=4×(-10648) - 3×(484) -5×-22 - 4

q(-22)=(-42592)-(1452)+(110)-(4)

q(-22)=(-42592-1452+110-4)

q(-22)= '-43938'

.

Hence, the value of polynomial q(t)=(-43938)
