Below are two different functions f(x) and g(x). what can be determined about their y-interceptions f(x)=2x-1

The y-intercept of f(x) is f(0), i.e. the value of f(x) when x=0.

y-intercept=f(0)=2(0)-1 =-1

Since g(x) is not given, we cannot determine its y-intercept.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
