Answer:
Step-by-step explanation:
f: y=x^2
g: y= -x^2
h: y= -x^2-5
first we transform the graph of f to the graph of g using the reflexion across y-axis .
then we transform of g to the graph of h using the translation -5( vector j )
look at the photo below for the graphics.

Answer:
Step-by-step explanation:
When subtracting fractions with the same denominator (bottom number[s]) you can treat the numerators (top number[s]) like subtraction with whole numbers.
is equal to -12. Therefore,
will equal
. But we're not there yet - this fraction can be simplified. We need to find the GCF, or greatest common factor, of -12 and 9. This would be another number that can be divided evenly into these two numbers. The first possible GCF that comes to mind is 3. Let's test that out:
It works! Now we can use this information to simplify the fraction. We replace -12 with -4 and replace 9 with 3. This gives us our final answer, .

y =
The focus of the solar oven's reflector is (0,a)
Step-by-step explanation:
The missing figure( i.e diagram) from the question is attached below:
Now ; given that :
The focus of the sun's rays is at a point L = 5 inches away from the vertex of the reflector. Also the distance of the parabolic curve be a= L = 5
So the equation for a cross section of the oven's reflector with its focus on the
positive y axis and its vertex at the origin is expressed as:
x² = 4 L y
x² = 4 (5) y
x² = 20 y
y =
The focus of the solar oven's reflector is (0,a)
