Answer:
Step-by-step explanation:
Given
Roots = -2 and 5
Required
Write the equation
We have that:
x = -2 and x = 5
Simplify further
x + 2 = 0 or x - 5 = 0
Multiply the results of the above
Open brackets
For solve equation by <span>graphing, it need to come equation at the form, that it's simple to build a graph for left part of equation, and another graph for right part. The intersection of thats two graphs is the solution.

Answer: D) h(x) = (1/4)x</h3>
This is the same as h(x) = x/4
In decimal form, it would be h(x) = 0.25x
=============================================
Explanation:
Inverses undo the original function. The original function tells us to take any input (x) and multiply by 4 to get the output y = f(x) = 4x
To get the inverse, we reverse the operation applied here. The opposite of multiplication is division. So we'll divide by 4 instead of multiply by 4. This is why the answer is x/4 or (1/4)x
-----------
Another approach is to do the following: Replace f(x) with y. Swap x and y. Solve for y
f(x) = 4x
y = 4x
x = 4y
4y = x
y = x/4
h(x) = x/4
We end up with the same result as before.
-----------
Extra info:
For any real number x, the following two equations are true
h( f(x) ) = x
f( h(x) ) = x
Y = 8x - 3
direct interpret it
