Answer:
Down
Step-by-step explanation:
The "parent function" is y = |x|, which opens up.
Changing the sign to y = -|x| flips (reflects) the graph over the x-axis, so the new graph opens down. Adding 9 shifts the graph up 9 units, but that does not change the way the graph opens.
See the attached image.
y = |x| purple
y = -|x| black
y = -|x| + 9 red
Answer:
The planes speed with be 430 mph
Step-by-step explanation:
triangle:
a plane figure with three straight sides and three angles.
rectangle:
a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
circle:
round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the centre).
cylinder:
solid geometrical figure with straight parallel sides and a circular or oval cross section.
cone:
surface or solid figure generated by the straight lines which pass from a circle or other closed curve to a single point (the vertex) not in the same plane as the curve.
Answer:
C
Step-by-step explanation:
Given the two functions, we need to find
(g ° f)(4)
This means, we need to put the function f(x) INTO the function g(x) and then evaluate that new function at x = 4.
We put the whole expression of f(x) into "x" of g(x). Shown below:
Now we plug in 4 into x and evaluate:
Thus,
correct answer is C
