Find the range of f(x) = -2x+6 for the domain {-1,3,7,9} HELLPPP!

Range: {-12, -8, 0, 8}

Step-by-step explanation:

To find the range of , plug in the value of each domain into the equation of the function to get the corresponding range value.

Given that the domain is {-1,3,7,9}, therefore:

✅

✅

✅

✅

Range would be: {-12, -8, 0, 8}

i do not know this sorry : (

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
