Yes it is it basically states that it’s a general result
It is a function because every input has exactly one output. It passes the vertical line test.
If you plotted another point at 2 hours it would no longer be a function bc 2 would be an input they had more than one output.

How to Find the Inverse of a Function
STEP 1: Stick a "y" in for the "f(x)" guy:
STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):
STEP 3: Solve for y:
STEP 4: Stick in the inverse notation, continue. 1 2 3.
Answer:The inequality is
x greater than or equal to(>/=) 14
Step-by-step explanation:
Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10
Assuming that Tara has paid at least her fair share, therefore
3x/10 = 4.20
3x = 4.20 ×10 = 42
x = 42/3 = 14
This means that the total cost of the pizza is at least $14. The inequality
how much the pizza could have cost becomes
x greater than or equal to(>/=) 14
