There is No Solution because I did this question because that’s make me brainliest please
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
Answer: i took the test its number 555555
Step-by-step explanation:
<span>To find the range of this function, simply plug each of the end values into the original equation. In this case, with x of -2, the function becomes f(x) = 6+1 or 7, and with x of 7, the function becomes f(x) = -21+1 or -20. As such, the range of the function is -21 <= f(x) <= 7.</span>
<u>Let's consider the facts at hand</u>:
- By Vertical Angle Theorem ⇒ ∠BCE = ∠DCF
- ∠BEC = ∠DFC
- Sides BE = DF
<u>Based on the diagram, triangles BCE and triangles DCF are similar</u>
⇒ based on the Angle-Angle theorem
⇒ since ∠BCE = ∠DCF and ∠BEC = ∠DFC
⇒ the two triangles are similar
Hope that helps!
<em>Definitions of Theorem I used:</em>
- <u><em>Vertical Angle Theorem: </em></u><em>opposite angles of two intersecting lines must be equal</em>
- <u><em>Angle-Angle Theorem:</em></u><em> if two angles of both triangles are equal, then the given triangles must be similar</em>
