Find the range of the function for given domain <br> f(x)=2x-7; (-2,-1,0,1,2)
Gelneren [198K]

Answer:

  {-11, -9, -7, -5, -3}

Step-by-step explanation:

Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.

__

  range = f(domain)

  = 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7

  = {-11, -9, -7, -5, -3} . . . . . the range for the given domain

_____

If you have a lot of function values to find, a spreadsheet or calculator can be helpful.

X^2 - 8x + 5 = 0
PtichkaEL [24]
<h2>Answer:</h2>

√44

2 Real Roots

<h2>Step-by-step explanation:</h2>

Looking at the image attached, the discriminant is the value under the square root.

In the equation given:

a = 1

b = -8

c = 5

The discriminant is therefore:

√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44

√44 is a positive number. Because it is positive, there must be 2 real roots.

If it were negative, there would be 2 imaginary roots.

If it were zero, there would be 1 real root.
