so the question is "an exponential function is defined by f(x)=a*b^x+c where b>0 and b isnt equal to one. the graph of f passes through the points (0,5), (1,17), and (3,377). which choice is the value of c?"
a. 2
b.3
c.5
d.-2
i typed the points into a table and hit the exponential regression, but it doesnt show me the value of c. am i doing sth wrong?
