Question

Can someone help me please!?

Evaluate the piecewise-defined 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).

Answer 1

x2 = x^2

Answer 2

@ sm101

for x>=0 what is f(x)=?
then what is f(5)=? and f(6)=?

Answer 3

I don't know... ??

Answer 4

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..

Answer 5

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).=___?

Answer 6

ok.. I'll try

Answer 7

ok good just plug into the formula f(x)=x^2 right?
