Factor the 25 where they multiply to make 25 and add to make 10 so now it's (x+5)and (x+5) so x=-5 because x+5=0 solved
Answer: Choice B) ![f^{-1}(x) = 2^x](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%202%5Ex)
Exponentials undo logarithms, and vice versa. The base of the log and the exponential are the same in this problem.
Answer:
49
Step-by-step explanation:
(4 × 10) + 9
= 49
Answer:
(f + g)(2)=14
Step-by-step explanation:
If f(x) = 2x^2 + 3x
g(x) = x - 2
(f + g)(2)
Lets find
(f+g) (x)
We add the 2 functions
(f+g) (x)=2x^2 + 3x + x - 2
Combine like terms
(f+g) (x)=2x^2 + 4x - 2
Now we let x=2
(f+g) (2)=2(2)^2 + 4(2) - 2
(f+g) (2)=2(4) + 8 - 2
=8+8-2
=14
Answer:
what's x?
Step-by-step explanation:
substitute whatever you have for x in the equation. I was taught f(x) is no different from y=.
