Step-by-step explanation:
we have two lines you have to draw.
one is all in the bottom left quadrant (for x<=0) and one in the upper right quadrant (for x>5).
the easiest is for x>5. the line function is only
f(x) = y = 3
so, this is a horizontal line on the grid line for y = 3. it starts above x=5 and then goes all the way to the right ("to infinity and beyond !"). just, if possible, mark the starting point at x=5 as a little empty "circle" instead of a full dot, as x=5 is explicitly excluded (due to x>5).
and for x<=0 the line
f(x) = y = 4x - 3
goes sharp down but goes a little bit to the left the further down it goes. it starts with x=0, which gives y=-3 per the function.
so, the starting point (with a full dot, as x=0 is included) is (0,-3).
from there it goes sharp down and a little bit to the left.
for example the next point is for x=-1, which gives y=-7, so it is the point (-1,-7). x=-2 gives y=-11 and the point (-2,-11).
the line has to go through so these points and further down (again, "to infinity and beyond !"), as to move further left on the negative x-axis.
Answer: y=(√x)/13 for x>0)
Step-by-step explanation: Y is f^-1(x) btw
Answer:
2d + 4 = 12
Step-by-step explanation:
d = # of daisies
d+4 = # of roses
The total number of flowers is 12, so:
d + d+4 = 12
2d + 4 = 12
Answer:
top box: ray
bottom box: endpoint
Step-by-step explanation:
top box: a ray is a line that doesn't stop and that is represented by a arrow on the end of it
bottom box: an end point is where a ray, or line segment stop and since i see two rays that stop there it is an endpoint
Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
