YOUR ANSWER


  • Graphical form: 2x%2B14 simplifies to 28
  • Text form: 2x+14 simplifies to 28
  • Cartoon (animation) form: simplify_cartoon%28+2x%2B14+%29
    For tutors: simplify_cartoon( 2x+14 )
  • If you have a website, here's a link to this solution.

DETAILED EXPLANATION

Look at 2%2Ahighlight_red%28+x+%29%2B14.
Replaced x with 7
It becomes 2%2Ahighlight_green%28+7+%29%2B14.
Look at highlight_red%28+2%2A7+%29%2Bhighlight_red%28+14+%29.
Replace constants in expression: highlight_red%28+2%2A7+%29,highlight_red%28+14+%29 with highlight_green%28+28+%29
It becomes highlight_green%28+28+%29.
Result: 28

DETAILED EXPLANATION

Look at 2%2Ahighlight_red%28+x+%29%2B14.
Replaced x with -2
It becomes 2%2Ahighlight_green%28+-2+%29%2B14.
Look at highlight_red%28+2%2A-2+%29%2Bhighlight_red%28+14+%29.
Replace constants in expression: highlight_red%28+2%2A-2+%29,highlight_red%28+14+%29 with highlight_green%28+10+%29
It becomes highlight_green%28+10+%29.
Result: 10

f(x)=2x+14
input: f(7), and f(-2)
-----
f(7) = 2*7+14 = 28
------
f(-2) = 2*(-2)+14 = 10
