What is the inverse of the function f(x) = x + 2?
nadya68 [22]

Answer: h(x)=x-2

Step-by-step explanation:

To find the inverse of the function f(x) = x + 2, the first  step is to replace f(x) with "y":

 f(x) =y= x + 2\\\\ y = x + 2

The second step is to solve for the variable "x":

x=y-2

The third step is to interchange the variables, then:

y=x-2

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

h(x)=x-2

10. The graph of y=f(x) is given below.y!24168848 xWhat is the possible degree of f?A. 4IB. -3C. 2D. 3E. -1
steposvetlana [31]

Answer:

The degree of the function is;

3

Explanation:

From the given graph, we can observe that the function has two extremum (one minima and one maxima).

The degree of the function will be the number of extremum plus 1;

\text{degree}=n+1

Since there are two extremum on the graph then;

\begin{gathered} \text{degree}=2+1 \\ \text{degree}=3 \end{gathered}

Therefore, the degree of the function is;

3

"Triangle XYZ is shown on the coordinate plane below. If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'
baherus [9]
Original points:
X (4,5)
Y (5,3)
Z (1,3)

When a point is reflected over the x-axis, its original coordinate (x,y) becomes (x,-y)

When a point is reflected over the y-axis, its original coordinate (x,y) becomes (-x,y)

I am assuming the triangle is reflected over the x-axis. But we have to consider that the line y = 1.

Point X (4,5) 

all things held constant, x' would have the coordinates (4,-5)

but line y = 1. So, x' (4, -3)

5 - 1 = 4 
1 - 4 = -3
