Answer:
45°
Step-by-step explanation:
Angles on a straight line add up to 180°.
135 + x = 180
x = 180 - 135
x = <u>45°</u>
Answer:
No, they are not.
Step-by-step explanation:
The easiest way to find a function on a graph is by finding if any points share the same x value. All of these do, so none are functions.
Answer:
The y-intercept is 6
Step-by-step explanation:
The y-intercept of a function is where the graph of an equation touches or crosses the vertical axis. This is usually the value of y when x = 0.
For this particular function, when x = 0 ⇒
f(0) = 0^2 + 4(0) + 6
= 0 + 0 + 6
= 6
Therefore, the y-intercept of this function is 6
