Find f(2) each of the following

1. f(x) = 3x-1

Solution

[tex]f(x) = 3x - 1 \\ f(2) = 3(2) - 1 \\ f(2) = 6 - 1 \\ f(2) = 5[/tex]

2. f(x) = -x+5

Solution

[tex]f(x) = - x + 5 \\ f(2) = - (2) + 5 \\ f(2) = 3[/tex]

3. f(x) = x²-1

Solution

[tex]f(x) = {x}^{2} - 1 \\ f(2) = (2)^{2} - 1 \\ f(2) = 4 - 1 \\ f(2) = 3[/tex]

4. f(x) = x-x³

Solution

[tex]f(x) = x - {x}^{3} \\ f(2) = 2 - {2}^{3} \\ f(2) = 2 - 8 \\ f(2) = 6[/tex]

5. f(x) = -|x|+2

Solution

[tex]f(x) = - |x| + 2 \\ f(2) = - |2| + 2 \\ f(2) = 4[/tex]

I hope it helps ^_^
