3. CALCULATOR Allowed for decimal approximation [VIPP #2] Solve the quadratic equations by using the Quadratic Formula. Solutions should be given in both simplified exact form and decimal approximation rounding to the tenths. Use correct formatting for your work (review the Quick Reference Sheet). It is always a good idea to check solutions (it is ok to use a calculator for the check). Show work. NOTE: The Quadratic Formula should be memorized to be prepared for Math 95. 4x² + 3x-2=0

Solutions in simplified exact form:

Solutions rounded to the tenths:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

it would be 6xy and -16xy.
