Answer:

C.Restricted domain :x\geq -4, f^{-1}(x)=-4+\sqrt{x-3}

Step-by-step explanation:

We are given that a function is not one - to-one.

f(x)=(x+4)^2+3

Suppose y=(x+4)^2+3

y-3=(x+4)^2

x+4=\sqrt{y-3}

x=\sqrt{y-3}-4

Hence, f^{-1}(x)=-4+\sqrt{x-3}

We know that domain of f(x) is converted into range of f^{-1}(x) and range of f(x) is converted into domain of f^{-1}(x).

Substitute x=3 then we get

f^{-1}(x)=-4

Domain of f^{-1}(x)=[3,\infty)

Range of f^{-1}(x)=[-4,\infty)

Domain of f(x)=[-4,\infty)

Restricted domain :x\geq -4

Hence, restricted domain of f(x) that makes the function one-to-one .

Solve 3x square - 2 x + 7 x - 5
ale4655 [162]

Answer:

The correct ans is...

3 x square + 5 x - 5

Step-by-step explanation:

U can only subtract or add if u hv the same variable..

here -2x and 7x have the same variable...

so -2x + 7x = 5x

Therefore the ans is....

3 x square + 5 x - 5

Hope this helps....

Have a GOOD DAY !!!!

Pls mark my ans as brainliest

If u mark my ans as brainliest u will get 3 extra points

Sry to say....

U really need to read ur Math TBK

5 (x minus 6) = 2 (x + 3)?
deff fn [24]

Answer:

12

Step-by-step explanation:

5(x-6)=2(x+3)

multiply

5*x and 5*6. 2*x and 2*3

5x-30=2x+6

minus 5x and 2x

3x-30=6

add 30 to 6

3x=36

divide both sides by 3 and the 3x cancels so 36÷3

x=12
