NEED HELP WITH THESE

f(x)=x^2-x+1
g(x) = 5 - 3x

Evaluate the following.
1) f(-1)
2)g( -8)
3)f( 1)
4) g(5)
5) f(3)
6) g(-3)

Answer 1

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

=1

5. f(x)=
`x^(2)`-x+1

f(3)=
`(3)^(2)`-3+1

= 9-3+1

=7

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
