2(x+6)<10 solve for x and inequality

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
