One graph is a linear function, the other is not.  A linear function will have an equation of the form $y = mx + b$, and will make a straight line for the graph.

The other function has an exponent in it, and will not make a straight line, unless graphed on a logarithmic scale.

You could choose some values for $x$ and evaluate the function and see if the resulting $y$ values matched the graph you are considering as your answer.

Are the graphs in the second image also part of the answer choices to the same problem?  If so, then you'll need to do some more reasoning or testing than simply the straight line/not straight line dichotomy.

I think if you evaluate $0.25*2^8$ you'll get the information you need to confirm your apparent answer choice.

Is it D?

whpalmer4 · Answer

Don't guess.  Evaluate the point I suggested, and see which graph fits.  If more than one graph has that point, evaluate another point.

$$y=\frac{1}{4}(2)^x$$
If x = 0, y = 1/4
If x = 1, y = 1/2
If x = 2, y = 1
If x = 3, y = 2
If x = 4, y = 4
If x  = 5, y = 8
If x = 6, y = 16
Choose the graph that contains those ordered pairs.

whpalmer4 · Answer

You can easily reject 2 of the graphs by evaluating the function at x = 0.
