Question

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).

f(–5) = –20, f(0) = –2

f(–5) = 10, f(0) = 0

f(–5) = 20, f(0) = 10

f(–5) = 12, f(0) = 5

Answer 1

f(–5) = 20, f(0) = 10

Explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10
