What is the vale of f(-4) f(x)=5+2|x| f(-4)=

f(-4) = 13

Put the value of x = -4 to the equation of the function:

f(x) = 5 + 2|x|

f(-4) = 5 + 2|-4| = 5 + 2(4) = 5 + 8 = 13

|a| = a for a ≥ 0

examples: |3| = 3, |0.5| = 0.5, |123| = 123

|a| = -a for a < 0

examples: |-3| = -(-3) = 3, |-0.5| = -(-0.5) = 0.5, |-123| = 123

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
