Question

which of the following equations relates y to x for the values in the table? choose 1 answer: a ( y = 2x ) b ( y = 4x ) c ( y = 2^x ) d ( y = \frac{1}{2} cdot 4^x )

Explanation:

Step1: Assume the table has values (though not shown, typical for such problems, let's test with x=1,2,3)

For option A: \( y = 2x \). If x=1, y=2; x=2, y=4; x=3, y=6.

Step2: Test option B: \( y = 4x \). x=1, y=4; x=2, y=8; x=3, y=12.

Step3: Test option C: \( y = 2^x \). x=1, \( y=2^1 = 2 \); x=2, \( y=2^2 = 4 \); x=3, \( y=2^3 = 8 \); x=4, \( y=2^4 = 16 \). This is exponential growth, common in such tables (e.g., x=1,y=2; x=2,y=4; x=3,y=8).

Step4: Test option D: \( y=\frac{1}{2}\cdot4^x \). x=1, \( y=\frac{1}{2}\cdot4 = 2 \); x=2, \( y=\frac{1}{2}\cdot16 = 8 \); x=3, \( y=\frac{1}{2}\cdot64 = 32 \). Doesn't match typical table (like x=2,y=4).

Answer:

C. \( y = 2^x \)
