Answer:
1. (-2,-4)
2. (3,2)
3. (-4,6)
4. (2,1)
5. (-3,17)
Step-by-step explanation:
To find the value of f(x), substitute the given value of x into the function and simplify.
1. f(x) = 3x+2; x = -2
f(-2) = 3(-2)+2
= -6+2
= -4
Ordered pair is (-2,-4)
2. f(x) = -x+5; x = 3
f(3) = -(3)+5
= -3+5
= 2
Ordered pair is (3,2)
3. f(x) = -2x-2; x = -4
f(-4) = -2(-4)-2
= 8-2
= 6
Ordered pair is (-4,6)
4. f(x) = 3x-5; x = 2
f(2) = 3(2)-5
= 6-5
= 1
Ordered pair is (2,1)
5. f(x) = -5x+2; x = -3
f(-3) = -5(-3)+2
= 15+2
= 17
Ordered pair is (-3,17)
Hope this helps!
