Step-by-step explanation:
I guess this means you have to "graph" (= draw the line) the functions.
it follows the same principle as in the answer of the other question :
we need to find the coordinates of 2 points, and then you draw the line through them.
b.
the first point is for me always x = 0 :
g(0) = -3/4 × 0 + 4 = 4
so, the first point is (0, 4).
and for the second point let's choose e.g. x = 4
g(4) = -3/4 × 4 + 4 = -3 + 4 = 1
so, the second point is (4, 1)
c.
again, as always, x = 0
y = -5×0 + 4 = 4
so the first point is again (0, 4).
for the second point let's pick e.g. x = 2
y = -5×2 + 4 = -10 + 4 = -6
so, the second point is (2, -6).
don't get confused by the name of the function (g, h, f, ...). it is just a name for the same principle.
and "y =" is standing for a function name like f(x). as "y" is the variable for functional result.
so, as before, mark the points and draw the lines through them.
