Here is the graph this quadratic function makes.
Answer:
<h2>
</h2>
Step-by-step explanation:
To find g-¹( 2) we must first find g-¹(x)
To find g-¹(x) equate g(x) to y
That's
y = g(x)
We have
y = - 2x + 7
Now interchange the terms that's x becomes y and y becomes x
We have
x = - 2y + 7
Make y the subject in order to find g-¹(x)
Move 7 to the left side of the equation
- 2y = x - 7
Multiply both sides by - 1
We have
2y = 7 - x
Divide both sides by 2 to make y stand alone
That's
<h3>
</h3>
So we have
<h3>
</h3>
Now to find g-¹(- 2) substitute the value of x that's - 2 into the expression
We have
<h3>
</h3>
We have the final answer as
<h3>
</h3>

Answer:
The kind of angle formed by perpendicular lines is 90°
Step-by-step explanation:
If two lines are perpendicular, to each other, then they meet at rightangles.
This means that, the measure of the angle between them is 90°.
Therefore, the kind of angle formed by perpendicular lines is 90°
