Begin by finding the lowest point the quadratic equation can be, the vertex;
x²-1= is just a translation down of the graph x²
vertex; (0, -1) and since the graph of x² would extend to infinity beyond that point, we can say {x| x≥0} for domain and {y| y≥-1}.
For the linear equation, it is possible to have all x and y values, therefore range and domain belong to all real numbers.
Hope I helped :)
Answer:
Recipe for a cup of lentils = 6 scoops
Recipes for a salad = 12 scoops
Step-by-step explanation:
Hannah is cooking enough lentils for lentil soup and a lentil salad. The soup recipe calls for ¾ cup of lentils. The salad recipe calls for 1 ½ cups of lentils. But Hannah only has a ⅛ measuring scoop.
How many scoops of lentils will Hannah need for both recipes?
a) Recipe for a cup of lentils
The soup recipe calls for ¾ cup of lentils.
Hannah only has a ⅛ measuring scoop.
Hence,
3/4 ÷ 1/8
= 3/4 × 8/1
= 6 scoops
Recipes for a salad
The salad recipe calls for 1 ½ cups of lentils.
Hannah only has a ⅛ measuring scoop.
Hence,
1 1/2 ÷ 1/8
= 3/2 ÷ 1/8
= 3/2 × 8/1
= 12 scoops
