Answer:
The value of the polynomial is -23.
Step-by-step explanation:
Given:
f(x) = -5x - 4x² + 3
To find:
Value of the given polynomial at x = 2
Solution:
To find the value of the polynomial at x=2, we substitute the value of x as 2 in it. Therefore,
f(x) = -5x - 4x² + 3
f(x=2) = -5(2) - 4(2)² + 3
f(x=2) = -10 -4(4) + 3
f(x=2) = -7 -16
f(x=2) = -23
Therefore, the value of the polynomial -5x - 4x² + 3 at x=2 is -23.
