Answer:
Let us take,
f(x) = 4x² - 5x + 3
When x = 1/2,
f (1/2)
= 4 (1/2)² - 5 (1/2) + 3
= 4 (1/4) - 5/2 + 3
= 1 - 5/2 + 3
= (2 - 5 + 6)/2
= 3/2

Step-by-step explanation:
4x²-5x+7
we know that
x=-1
now, put the value of x in the given equation
4x²-5x+7
= 4(-1)²-5(-1) +7
= -4 +5+7
= 8
hence, the value of the polynomial 4x²-5x+7 is
8.
