On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 3). What is the value of a for the exponential function in the graph represented in the form of f(x) = a(bx)? −4 −3 3 4

3

Step-by-step explanation:

f(x)=a*b^x - is a formula of exponential function

As we know the point (x=0; y=3) lies at the function's  graph.

So we have to put in formula f(x)=a*b^x   x=0  f(x)=y=3

3=a*b^0   (b^0=1) => 3=a*1 => 3=a  

40 x 50 = 2000
