Answer:
f(x) = x
Step-by-step explanation:
note : slope is positive 1, so the x term must be positive
also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .
if we substitute this into the general equation for a line
y = mx + b, where m = +1 and b = 0,
we get y = x
or f(x) = x (in function form)

Answer:
Step-by-step explanation:
Step one:
the original price of refrigerator = $650.20
the markup/raise is 50%
the new price after the raise is
= 50/100*650.20
=0.5* 650.20
=325.1
The raise is by $325.1
The new price is $325.1+ $650.20=$975.3
Step two:
there was a discount of 70%
so =(70/100)*975.3
=0.7*975.3
=682.71
The discounted price is $682.71
The new price is 975.3-682.71
=$292.59
