Find the sum of 2x 2 + 3x - 4, 8 - 3x, and -5x 2 + 2

(2x² +3x -4) + (8 -3x) + (-5x² +2)

= x²(2 -5) +x(3 -3) +(-4 +8 +2)

= -3x² +6

The process here is called "collecting terms", which means you add the coefficients of "like" terms. Terms are "like terms" when they have the same constellation of variables. Here, there are three different kinds of like terms:

• x² terms

• x terms

• constants

This process is an application of the distributive property, as you can see on the second line of the solution above.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
