Please explain step-by-step. If you don't explain, don't even bother answering.

Answer:

45°

Step-by-step explanation:

From the diagram :

∠AOC = ∠AOB + ∠BOC
96 = 9x - 75 + 8x - 67
17x - 142 = 96
17x = 238
x = 238/17
x = 14

Finding ∠BOC :

∠BOC = 8x - 67
∠BOC = 8(14) - 67
∠BOC = 112 - 67
∠BOC = 45°

Step 1. Function is vertically stretched by a factor of 3:

y = 3 * | x |

Step 2. Shifted two units left:
