math help needed?

Question

A question i have says find all values of x that satisfy the equation f(x)=4?
the equation is f(x)=(x+3 -1 lessthanequal x less thanequal 2
4-x 2 lessthan x lessthan 8
-(x-10)squared x greaterthanequal 8
Please help what do i do i dont understand

Answer 1

This is completely incomprehensible. Please copy out the question exactly as it is in the book/paper, and we will try to help you with it. For X squared, type X^2. Use parentheses to clarify if needed.

If f(x) is to = 4, and f(x) = some other equation, then you are looking for the answer where 4 = some other equation.

Answer 2

If you mean
f(x) = 4
f(x) = (x+3)
-1 <= x <= 2
4 - x^2 < x < 8
-(x-10)^2 > x >= 8

You have to graph each of the lines:
y = 4
y = x+3
-1 <= x <= 2 (will be all values from -1 to + 2)
etc. Then see where they all intersect or what areas they all have in common.

For "greater than or equal to" or "less than or equal to"
you need to "shade" the graph for all values either greater
than or less than the endpoints.

Then to find the values that satisfy all, you need to see where these intersect, and only choose THOSE values. If any value is shaded for two or more of the equations, but not all of them, then that value is not part of the answer. The right answers will make all of them true. If you want, you can check your answer by plugging some of the values into the equations, and making sure they really work.

Note: The last two equations are missing some words or signs.
You need to get some help, as this is better shown to you by someone who can draw and shade the graph with you. Can you find a tutor or another student in the class to show you an example?
