Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
- If the vertical line crosses the graph in more than one point, then the graph does not represent a function
- If the vertical line crosses the graph in only one point in different positions, then the graph represents a function
The horizontal line test is used to show that the function has an
inverse or not
- If the horizontal line crosses the graph of a function in more than one point, then the function has no inverse
- If the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverse
Let us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.

dont rlly inderstand this need more understanding
Step-by-step explanation:
<span>The original cost of the camera is $120.
Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.
We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.
Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>

Hope This Helps and God Bless!
Answer:
d=125-degree since p and q are parallel
b=d=125-degree since b and d are vertically opposite angles
a+d= 180-degree since they lie in straight line
Hence, a=180-125=55-degree
c=a=55-degree since a and c are vertically opposite angle
f=a=55-degree since a and f are alternate angle
e=f=55-degree since e and f are vertically opposite angle
