Answer:
- 8x + 9
Step-by-step explanation:
To evaluate g(2x - 1) substitute x = 2x - 1 into g(x), that is
g(2x - 1)
= - 4(2x - 1) + 5 ← distribute parenthesis and simplify
= - 8x + 4 + 5
= - 8x + 9
She is wrong she should have added 18 to both sides
Log16 4 = 2
log base 16 then the number four then set that equal to 2

Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational
Answer:
The value of g'(10)=
Step-by-step explanation:
Given function is f(x)=
Take f(x)=y
y=
Subtract 2 from both side.
y-2=
x=
The inverse of f(x) is written as 
It is said as g is inverse of f
g(y)=\frac{4}{y-2}[/tex]
g(y)=
g(10)=
g(10)=
Differentiating both sides we get,
g'(y)=
g'(y)=
To find g'(10)=
g'(10)=
