Hello,

if f(x)=y=x+3

x=y+3==>y=x-3

f^(-1) (x)=x-3 is the inverse function of f(x).

3. For the function, :c(X)=x^2+4x-5 over x+5<br> (a) Identify the restricted domain value(s).
Mrrafil [7]
Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.

x + 5 = 0
x = -5
The restriction is that x cannot equal -5.

Find the value of x <br>​
den301095 [7]

x = 20 is the answer.

<u>Step-by-step explanation:</u>

When a parallel lines cut by a transversal, then the alternate exterior angles are congruent.

So the given 2 angles add up to 180 degrees.

5x+ 9 + 3x+ 11 = 180

8x + 20 = 180

8x = 180 - 20 = 160

  x = 160/8 = 20

If x varies directly with y and x = 2.5 when y = 10, funny x when y = 16.
amid [387]

Answer:

Should be 4.0(Not sure tho. my thought process is complicated but to me it makes sense)

Step-by-step explanation:

If y=10 and x =2.5, if y were to = 20, then x would equal 5. so you take that ratio, and say 6 is 3/5's the way to 10, so you also divide 2.5 by 3/5

you get 1.5, you add that to x already and you get 4.0

so if y=16, x should =4.0
