X = -3,2,5,11
F(x) = -130,0,78,234
Which function represents f?
f(x) = 26 (x - 2)
f(x) = -26 (2x - 1)
f(x) = 13 (x - 2)
f(x) = -2 (26x - 1)
To determine which function represents f, we can plug in the given values of X and F(x) to see which function produces the correct output.
Using f(x) = 26 (x - 2):
f(-3) = 26(-3 - 2) = 26(-5) = -130
f(2) = 26(2 - 2) = 26(0) = 0
f(5) = 26(5 - 2) = 26(3) = 78
f(11) = 26(11 - 2) = 26(9) = 234
This matches the given values of F(x), so f(x) = 26 (x - 2) is the correct function representing f.
