Question

which of the following functions is represented by a graph A. identity y=xB. reciprocal y=1/xC. constant y=cD. exponential y=b^x

Answer 1

Notice that the given graph represents a line that passes through the origin, and the points on the graph are of the form:

$(a,a)\text{.}$

Therefore the function that is represented by the given graph is:

$y=x\text{.}$

Answer: Option A.
