If f(x) = x^2 + 9 and g(x) = 24 + 4x, what is the value of f(4) / g(-1)?
F. 0.75
G. 0.8
H. 1.2
J. 1.25
K. 1.75
f(4) = 16+9 = 25
g(-1) = 24-4 = 20
so what is the problem?
J. 1.25
yes
Thank you
To find the value of f(4), we need to substitute the value of x with 4 in the function f(x) = x^2 + 9.
f(4) = (4)^2 + 9
= 16 + 9
= 25
Next, we need to find the value of g(-1) by substituting x with -1 in the function g(x) = 24 + 4x.
g(-1) = 24 + 4(-1)
= 24 - 4
= 20
Now, we can calculate f(4) / g(-1):
f(4) / g(-1) = 25 / 20
= 1.25
Therefore, the value of f(4) / g(-1) is 1.25.
The correct answer is J. 1.25.
