## ZachBO$$2 years ago If f(x) = 0.5(1 – x), what is the value of f(–1)? • This Question is Open 1. ajprincess plug in -1 in place of x in f(x)=0.5(1 – x). Does that help? 2. ZachBO$$

yes but no

3. ajprincess

f(x)=0.5(1 – x) f(-1)=0.5(1-(-1))

4. ZachBO$$so what is do is, 0.5 (1-(-1)), i do that math problem to find the answer? 5. ajprincess 0.5 (1-(-1))=? 6. ZachBO$$

i dont understand how to work it out

7. ajprincess

what is 1-(-1)?

8. ZachBO$$-2? 9. ZachBO$$

am i right

10. ZachBO$$sorry, it is 2 because two negatives makes a positive so it would be 2, am i correct 11. ajprincess yup u r right:) nw multiply 2 by 0.5. 2*0.5=? 12. ZachBO$$
