Question

EXERCISE - 2.2
1. Find the value of the polynomial 4x² – 5x +3, at
x=-1​

Answer 1

Step-by-step explanation:

f(x)=4x² – 5x +3,

f(x)=4x² – 5x +3,f(-1)=4×(-1)^2-5(-1)+3

f(x)=4x² – 5x +3,f(-1)=4×(-1)^2-5(-1)+3 =4+5+3

f(x)=4x² – 5x +3,f(-1)=4×(-1)^2-5(-1)+3 =4+5+3 =12

have a nice day

Answer 2

Answer:

p(-1)=4x^2-5x+3

=4(-1)^2-5(-1)+3

=4(1)+5+3

=4+5+3

=12
