Answer:

  9.  a = 3, b = 3, y-intercept = 3

  10.  a = 5, b = 0.6, y-intercept = 5

Step-by-step explanation:

The picture is fuzzy, but we think the given equations are ...

  $\text{9. }f(x)=3(3)^x\\ \text{10. }f(x)=5(0.6)^x$

You are comparing these to the form ...

  $f(x) = a(b)^x$

so the values of 'a' and 'b' should be readily identifiable. The y-intercept in each case is y = a.

The end behavior depends on whether b > 1 or not. Growth functions (b>1) go to 0 on the left and ∞ on the right. Decay functions (b<1) are the reverse.

9. a = 3, b = 3, y-intercept = 3

The end behaviors are (x, f(x)) ⇒ (-∞, 0), (∞, ∞).

10. a = 5, b = 0.6, y-intercept = 5

The end behaviors are (x, f(x)) ⇒ (-∞, ∞), (∞, 0).
