What are the values of f(x) = 9^x when x= -2? a) 1/81 b) 81 c) 1/18 d) 18

(a)

Step-by-step explanation:

using the rule of exponents

• ⇔ , hence

= = → (a)

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
