  +70 or -70, depending on how you rewrite the equation

Step-by-step explanation:

A quadratic equation in standard form can be written as ...

  ax² +bx +c = 0

When this equation is written in standard form, it could be either of ...

  17x² +30x +40 = 0 . . . . . . . . . . add 17x²+30x to both sides

or

  -17x^2 -30x -40 = 0 . . . . . . . . . subtract 40 from both sides

__

In the first case, a = 17, b = 30, c = 40 and (b+c) = 70.

In the second case, a = -17, b = -17, c = -40 and (b+c) = -70.

Additional comment

I personally prefer a positive leading coefficient, but it is less work to subtract 40 from both sides than to subtract 2 terms from both sides. Check your curriculum materials for the preferred rewrite in this case.

step-by-step explanation:

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
