How do I solve this

Question

Evaluate the function for the given values.

h(x) = [[x+3]]

a. h(-2)

b. h(1/2)

c. h(4.2)

d. h(-21.6)

Answer 1

Wherever you see x substitute the given value for h(x)

so h(-2) = (-2 +3 )= 1

h(1/2) = (1/2 +3 ) = 3 1/2 or 7/2

h(4.2) = (4.2 +3) = 7.2

See if you can do the last one
