Answer:
Question 1
<u>Given</u>
<u>Use formula and solve for x:</u>
- SP = CP + P
- 144 = x + (20% of x)
- 144 = x + 0.2x
- 144 = 1.2x
- x = 144/1.2
- x = 120
Cost price is N 120
Question 2
<u>Given</u>
- SP = 1000
- P = -20% (negative because of loss)
- CP = x
<u>Use formula and solve for x:</u>
- SP = CP + P
- 10000 = x - (20% of x)
- 10000 = x - 0.2x
- 10000 = 0.8x
- x = 10000/0.8
- x = 12500
Cost is N 12500

a co mam zrobic!!!!!!!!!!!!!!!
bo nie wiem!!!!!!!!!!!!
Step-by-step explanation:
Range for the given Exponential function
is f(x) > 0.
the correction option is a). f(x) > 0
The function given in, the question is exponential function is given by
Which is an exponential function. The domain of the give function is (-∞, ∞).
<h3 /><h3>what is exponential function?</h3>
The function which is in format f(x) =
where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
the Question seems to be incomplete. And options could be
a) f(x) > 0 c) f(x) ≤ 0
b) f(x) < 0 d) f(x) ≥ 0
Simplification of the given equation


clearly, the range of the exponential function is f(x) > 0.
