Question

Easy points just answer correctly

Give the values of b, h, and k for the function f(x) = log_5 (x - 4) – 1 .
b = 5, h = -4, and k = 1
b = 5, h = 4, and k = 1
b = 5, h = 4, and k = -1
b = 5, h = -4, and k = -1

Answer 1

General equation

• log_b(x+h)-k

Here our equation

• log_5(x-4)-1

So

• b=5
• h=-4
• k=1

Answer 2

• D. b = 5, h = - 4, k = - 1

Explanation:

Translated of logarithmic function:

• 
  `f(x) = log_b (x + h) + k` where b is base, h - horizontal shift, k - vertical shift

According to given function the values are:

• b = 5, h = - 4, k = - 1

Correct choice is D
