Which graph represents the piece wise- defined function f(x) =

Step-by-step explanation:

The given piecewise function is

Notice that the domain of the function specifies that, from zero to three, the function represents a decreasing (because the variable is negative) straight line. When the function is defined from 3 to infinite, the function is a constant of 5.

So, the right graph must shows first a decreasing line, where the initial point is solid and the final point is empty, as the fourth fraph (from left to right), then it must show a horizontal line with an initial point solid.

Therefore, the fourth graph, from left to right, is the correct answer.

right-most fourth graph

Step-by-step explanation:

Given:

f(x)= -x+4    for 0≤x<3

i.e. from x=0 till x=3 the graph is linear line

then

f(x) = 5        for x≥3

i.e. at x=3 and onward graph is a straight line with y-axis point of 5 !

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
