Can someone help me please!?
Evaluate the piecewisedefined function for the given values.
If f(x) =
x for x ≥ 0
x2 for x < 0
, find f(5), f(6), f(−2), and f(−3).

for x>=0 what is f(x)=? it is f(x)=x just use the formula given then what is f(5)=? and f(6)=?.... f(5)=x and f(6)=6..

next f(x)=x^2 for x<o use this formula for x<0 w/c is x=2 and x=3 therefore f(−2)=___?), and f(−3).=___?

I'm not sure how to substitute the f(5) and to come up with a solution

ok the picewise prob means that for x>=0 the formula you have to use is f(x)=x and for x<0 the formula you have to use is f(x)=x^2

that is for the piecewise formula here If f(x) = x for x ≥ 0 =x2 for x < 0

. If f(x) = x for x ≥ 0, the given are x=5 and x=6, therefore f(5)=5 and f(6)=6 now for f(x) =x^2 for x < 0, the given are x=2 and x=3 therefore f(x) =x^2 f(2)=___? and f(3)=___?

what is f(5) and f(6) though?
 one year ago

mark_o. Group TitleBest ResponseYou've already chosen the best response.1
use the formula for f(x)>=0 ,,,f(x)=x therefore f(5)+__? and f(6)=___? look up there and read, what we have done up there before.... :D

I did.. but I'm confused lol f(5)+? f(6)=6
