Consider the function f(x)=x^2+bx-49 where b is a constant. if the function has an axis of symmetry at x = 8, what is the value
Jlenok [28]
For this case we have the following equation:
 f (x) = x ^ 2 + bx-49
 Deriving we have:
 f '(x) = 2x + b
 We match zero:
 0 = 2x + b
 We clear x:
 x = -b / 2
 The axis of symmetry is at x = 8, therefore:
 x = -b / 2 = 8
 Clearing b:
 b = -2 * (8)
 b = -16
 Answer:
 
the value of b is:
 
b = -16

I NEED YOUR HELP IF YOU KNOW HOW TO DO IT OR EVEN HAVE A GREAT QUESS I WOULD LOVE TO HEAR IT SO PLEASE HELP ME PLEASE
Brut [27]

Answer:

±1,±1/3,±5,±5/3,±25,±25/3

Step-by-step explanation:

Rational roots test (p/q)

p= factors of constant

q= factors of number with highest degree

In this equation, the number with the highest degree (power) is 3.

The factors of 3 are 3 and 1.

The constant term is 25.

Factors of 25 are 25, 1, 5, 5

so, basically,

p/q = factors of constant/ factors of number w/ highest degree.

25, 1, 5/ 3,1

so, 25/3, 25/1, 1/3, 1/1, 5/3, 5/1
