Question

Which function is graphed on the right?

y = 2x+3 – 2

y = 2x–3 + 2

y = 2x–2 + 3

y = 2x–2 – 3

Answer 1

C. y = 2x–2 + 3

Explanation:

its correct

Answer 2

y = 2^(x–2) + 3

Explanation:

The equation above is the one that is graphed. You can pick it from the offered choices by recognizing that the horizontal asymptote on the graph is y=3. That is 3 units above the horizontal asymptote of the parent exponential function. Hence, you must have ...

y = (some exponential) +3

_____

Please note that the exponent indicator (^) and the grouping parentheses on the exponent are essential. Without those, the equation is that of the line y=2x+1, which is not what is graphed.
