Just substitute the value of x back into the function.
So,

becomes


So, f(-3) is equal to 10.
Answer:
<h2 />
Step-by-step explanation:
x y
1 2
2 4
3 9
4 16
This sounds like a quadratic equation of f(x)=x^2, thus, the range is:
<h3>
R(x): (-∞,+∞)</h3><h3 /><h3>
If the function only has these points, then the range is:</h3><h3>
R(x): [2]∪[4]∪[9]∪[16]</h3>
Answer:
Step-by-step explanation:
<u>Given:</u>
- Cost price = $16.50
- Mark up rate = 120%
<u>Selling price is:</u>
- $16.50 + 120% =
