let f(x) = 2x-1 for <5 and x^2-3 for x=5

Question

Then it says determine f(-2) f(0) f(1) f(5) and f(10) Im not sure how to work this

Answer 1

the function f(x) is defined in to different ways depending on the value of X.

 

When x is < 5, use the expression 2x - 1 to evaluate the function

 

When x is ≥ 5, use the expression x² - 3

 

for example

 

f(1) = 2(1) - 1 = 1

 

f(10) = (10)² - 3 = 97

 

can you do the other ones?
