Find the inverse of the function.<br> f-^1(x)= (x – 5)^3 + 1
Cloud [144]

Answer:

Step-by-step explanation:

To find the inverse of function y=f(x), swap variables and then solve for the original variable.

y=(x-5)^3+1\\ \\ x=(y-5)^3+1\\ \\ x-1=(y-5)^3\\ \\ \sqrt[3]{x-1}=y-5\\ \\ y=\sqrt[3]{x-1}+5\\ \\ f^{-1}(x)=\sqrt[3]{x-1}+5

3x - 4 &lt; 8 and 2x+ 2 &gt; 4<br> 20 points crq
Gekata [30.6K]

Answer:

x<4 and x>1

Step-by-step explanation:

1) 3x-4<8

Add 4 to both sides first to isolate x.

3x-4<8

  <u>+4 +4</u>

3x<12

Divide both sides by 3.

3x<12

<u>/3  /3</u>

x<4

2) 2x+2>4

Subtract both sides by 2 to isolate x.

2x+2>4

   <u>-2  -2</u>

2x>2

Divide both sides by 2.

2x>2

<u>/2  /2</u>

x>1

Hope this helped!! Have an amazing day :3
