Question

the graph of g(x) is the graph of f(x)=x−2 reflected across the y-axis.
which equation describes g?
g(x)=−2x+2
g(x)=−x+2
g(x)=x+2
g(x)=−x−2

Answer 2

drawing a rough diagram will help

Answer 3

they both have y intercept at -2
and
the slope has the same numerical value as f except that its negative.

Answer 4

recall that a straight line has general equation

y = mx + b where m = slope and b is the intercept on y axis
