Answer:
f(x+2)=3x+10
Explanation:
f(x+2) means replace all the xs with (x+2)
f(x)=3x+4
f(x+2)=3(x+2)+4
Now simplify
f(x+2)=3x+6+4
f(x+2)=3x+10
Answer:
Step-by-step explanation:
-0.5
Step-by-step explanation:
If x is 1, plug it into the equation.
So, y=-3(1) + 2.5
-3(1) = -3
now add.
-3+2.5 = -0.5
so that should give you y = -0.5
Answer:
17/24
Step-by-step explanation:
The inverse of this function is y = ![\frac{ln(x + 9)}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bln%28x%20%2B%209%29%7D%7B2%7D%20%20)
You can find the inverse of any function by switching the x and y values. Once you've done that, you can solve for the new y. The result will be the inverse of the function. The work for this one is below.
y =
----> Switch the x and y
x =
-----> Add 9 to both sides
x + 9 =
----> Take the natural log (ln) of both sides. This will case the e to cancel on the right side.
ln(x + 9) = 2y ----> Divide both sides by 2.
y = ![\frac{ln(x + 9)}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bln%28x%20%2B%209%29%7D%7B2%7D%20%20)
This will be your inverse function.
