Choose the graph that shows the correct sum.

The graph that shows the correct sum is:

                       Graph B

Step-by-step explanation:

We are given a graph of a function f(x) as a straight line that passes through (0,2) and (2,0).

Hence, the equation of f(x) is:

Also the graph of g(x) is a upward open parabola with vertex at (0,-3)

Hence, the equation of g(x) is:

Now the sum function i.e. (f+g)(x) is given by:

Hence,

    Hence, the graph that denotes this function is:

                           Graph B.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
