Hi! Let's go over the meanings of each term to find our answer.
Domain of an exponential parent function - the set of all real values of x that will give real values for y in the given function
Range of an exponential parent function - the set of all real values of y that you can get by plugging real numbers into x in the same function
Now we have our answers! All we had to do was go over the meanings, or definitions.
Hope this helps!

Can be linear because you add 4 to the x and add 1 to the y
The graph makes it evident that the axis of symmetry is the line x = 2. To algebrically show work, you’d need to use the formula x = -b/2a for a quadratic function in standard form. Remember, the axis is the vertex’s X value
Answer:
3x - 3
Step-by-step explanation:
(x + 4) + (2x - 7) =
The first step is to drop the parentheses since they are unnecessary.
= x + 4 + 2x - 7
Now group like terms together.
= x + 2x + 4 - 7
Combine like terms.
= 3x - 3
There are 150 teachers because 20 * 150 is 3000.
