Hello!
To find the maximum value of the function f(x) = -3(x - 10)(x - 4), the easiest way is to find the vertex using the formula: x = -b/2a.
Firstly, we need to simplify f(x).
f(x) = -3(x - 10)(x - 4)
f(x) = -3(x² - 14x + 40)
f(x) = -3x² + 42x + -120
Since the equation f(x) is now simplified to standard form, we can find the vertex.
a = -3, b = 42, and c = -120
x = -(42)/2(-3) = -42/-6 = 7
Then, we substitute 7 into the the function f(x) = -3(x - 10)(x - 4), or
f(x) = -3x² + 42x + -120, to find the y-value of the vertex.
f(x) = -3(7 - 10)(7 - 4)
f(x) = -3(-3)(4)
f(x) = 27
The vertex of f(x) is (7, 27).
Therefore, the maximum x-value for the function f(x) is 7.

Answer:
Local maximum = [3, 4]
Step-by-step explanation:
Step 1: Plot the given points [–1, 0] [1, 2] [2, 3] [3, 4] and draw the graph.
Step 2: Observe the graph, it is a straight line. Which has local minimum and local maximum at the closed interval.
Here with I have attached the graph.
The graphed function at local maximum at [3, 4]
Thank you.
You need to make the bottom fraction a common multiple !!
