I need help with this?

y = 3( )

Step-by-step explanation:

Exponential function has the form f(x) = k where b > 0 and b ≠ 1

~~~~~~

3 = k × ⇒ k = 3

1.5 = 3( ) ⇒ b = 0.5

Thus, y = 3( )

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
