Answer:
<u>3rd graph (on bottom left)</u>
Step-by-step explanation:
First, find the <u>zeros of the function</u>.
- f(x) = x² - x - 2
- f(x) = x² + x - 2x - 2
- f(x) = x(x + 1) - 2(x + 1)
- f(x) = (x - 2)(x + 1)
The zeros are :
- x - 2 = 0 ⇒ x = 2
- x + 1 = 0 ⇒ x = -1
Therefore, the graph of the function intersects the x-axis at :
The correct graph is <u>3rd graph (on bottom left)</u>
Answer:
x = 19
Step-by-step explanation:
x + (x + 4) + (3x - 9) = 90°
Combine like terms
5x - 5 = 90
Add 5 on both sides
5x = 95°
Divide 5 on both sides
x = 19
