Means, for every 1 input, there is 1 coresponding output
normally x is input and y is output in form (x,y)
so just look for the option(s) that has/have every first number repeat with only 1 2nd number

A. -7 repeats with 5 and -3, not a function

B. no repeats of first number (6,-8) and (-5,-8) are fine because first numbers don't repeat, das is funciton

C. no repeats, function

D. no repeats, function


answer is B,C,D

Answer:

\fbox {x-intercepts : (1, 0) and (-3, 0)}

\fbox {Roots : x = 1, x = -3}

Step-by-step explanation:

<u>Given</u> :

  • y = 4x² + 8x - 12

4 cancels throughout.

  • <u>y = x² + 2x - 4</u>

<u>Solving by quadratic formula</u> :

  • x =  -8 ± √(8)² - 4(4)(-12) / 8
  • x = -8 ± √64 + 192 / 8
  • x = -8 ± √256 / 8
  • x = -8 ± 16 / 8
  • x = -1 ± 2
  • x = 1 and x = -3

∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.
