Answer 1

You need to interpolate the value of category.category_image

<%= link_to servicecategories_path(slug: category.slug ),  
            class: "category-item" do %>

  <div style="background-image: url(<%= asset_path('category.category_image') %>)">
    <h3> <%= category.name %></h3>
  </div> 

<% end %>

Answer 2

You seems to have the incorrect syntax to use the rails interpolation inside the style attribute, Try this,

 <%= link_to servicecategories_path(slug: category.slug ),
 :style=>"background-image: <%= asset-data-url(category.category_image) %>",
   class: "category-item" do %>

Answer 3

this works

<%= link_to servicecategories_path(slug: category.slug ),  
            class: "category-item" do %>

  <div style="background-image: <%= asset_path('category.category_image') %>">
    <h3> <%= category.name %></h3>
  </div> 

<% end %>
