advanced-mathThe graph shows two functions. Which statement is true?
A
Both are exponential
B
The red curve is linear, blue is exponential
C
The blue curve is linear, red is exponential
D
Both are linear
Correct Answer: C
Choice C is the correct answer. Identify the curve shapes.
- Blue Curve: Straight line → Linear function.
- Red Curve: Curved, getting steeper → Exponential growth.
- Key Difference: Linear has constant slope, exponential has increasing rate of change.
💡 Strategic Tip: Exponential graphs curve sharply upward (growth) or downward (decay), while linear graphs are straight lines.
Choice A is incorrect because one curve is clearly straight (linear). Choice B is incorrect because it reverses which curve is which. Choice D is incorrect because the red curve is not straight.
