Answer:
110 Degrees
Step-by-step explanation:
Every interior triangle equalls 180 degress. So you subtract what you already have from 180.
30+40+x=180
70+x=180
180-70=110

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 2x²
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = 2(-3)²
- Exponents: f(-3) = 2(9)
- Multiply: f(-3) = 18
Option a is not a function because for x = 0, y = 3 and 4.
option b is a function.
option c is not a function because for x = 2, y = 1 and 8.
option d is not a function because for x = 1, y = -3 and 4
