P= 4.3(1.02) 4. In Canada the population of children in the age group 0-14 years has
been declining by 0.7% per year. The population of this age group in
1999 was about 5 917 000.
a. Write an exponential function to model this decline.
b. How many children would there be today?

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
