NEED HELP WITH THESE

faltersainse [42]

Step-by-step explanation:

1 .f(x)= $x^{2}$ -x+1

f(-1)= (-1)-(-1)+1

f(-1)= 1+1+1

= 3

3.f(x)= $x^{2}$ -x+1

f( 1)=(1)-1+1

f( 1)=1-1+1

5. f(x)= $x^{2}$ -x+1

f(3)= $(3)^{2}$ -3+1

= 9-3+1

2. g(x) = 5 - 3x

g( -8)=5-3(-8)

g( -8)=5+24

=29

4.g(x) = 5 - 3x

g(5)=5-3(5)

g(5)=5-15

=-10

6.g(x) = 5 - 3x

g(-3)=5-3(-3)

g(-3)=5+9

=14
