A piecewise function is shown here:
prohojiy [21]

f(0) = -3(0) + 5 = 5

f(-4) = -3(-4) + 5 = 17

f(6) = ½(6) - 4 = -1

f(9) = 2

f(2) = ½(2) - 4 = -3

Using the restraints, find which equation the f(x) function validates and plug it in.

Find the values of y = c(x) = for x = 0, 0.008, 0.027, 0.064, 0.125, 0.216, 0.343, 0.512, , 0.729, and 1.
kondaur [170]

c(x) is a function, then we will solve the problem for two different functions.

1. If c(x)=\frac{x}{0.5}+x

Then

y=c(x)

y=\frac{x}{0.5}+x

Using each of the values for x we have.

When x=0 the result is:   y=\frac{0}{0.5}+0=0

When x=0.008 the result is: y=\frac{0.008}{0.5}+0.008=0.016+0.008=0.024

When x=0.027 the result is: y=\frac{0.027}{0.5}+0.027=0.054+0.027=0.081

When x=0.064 the result is: y=\frac{0.064}{0.5}+0.064=0.128+0.064=0.192

When x=0.125 the result is: y=\frac{0.125}{0.5}+0.125=0.25+0.125=0.375

When x=0.216 the result is: y=\frac{0.216}{0.5}+0.216=0.432+0.216=0.648

When x=0.343 the result is: y=\frac{0.343}{0.5}+0.343=0.686+0.343=1.029

When x=0.512 the result is: y=\frac{0.512}{0.5}+0.512=1.024+0.512=1.536

When x=0.729 the result is: y=\frac{0.729}{0.5}+0.729=1.458+0.729=2.187

When x=1 the result is: y=\frac{1}{0.5}+1=2+1=3

2. If c(x)=sin(x)+2x

Then

y=c(x)

y=sin(x)+2x

Using each of the values for x we have.

When x=0 the result is:   y=sin(0)+2(0)=0

When x=0.008 the result is: y=sin(0.008)+2(0.008)=0.000139+0.016=0.016139

When x=0.027 the result is: y=sin(0.027)+2(0.027)=0.000471+0.054=0.054471

When x=0.064 the result is: y=sin(0.064)+2(0.064)=0.001117+0.128=0.129117

When x=0.125 the result is: y=sin(0.125)+2(0.125)=0.002182+0.25=0.252182

When x=0.216 the result is: y=sin(0.216)+2(0.216)=0.003769+0.432=0.435769

When x=0.343 the result is: y=sin(0.343)+2(0.343)=0.005986+0.686=0.691986

When x=0.512 the result is: y=sin(0.512)+2(0.512)=0.008936+1.024=1.032936

When x=0.729 the result is: y=sin(0.729)+2(0.729)=0.012723+1.458=1.470723

When x=1 the result is: y=sin(1)+2(1)=0.017452+2=2.017452
