Answer:
On a coordinate plane, a cosine curve has a maximum of 4 and a minimum of negative 2.
Step-by-step explanation:
Given: 
To find: maximum and minimum of the cosine curve
Solution:
A coordinate plane is a two-dimensional plane formed by the intersection two axis: x-axis and y-axis.
These two axes are perpendicular to each other.
As per the image drawn below,
a cosine curve has a maximum of 4 and a minimum of negative 2 on the coordinate plane.
Answer:
B. D. E
Step-by-step explanation:
Answer:
if I did it correctly then it is y= 1/4x-9/4
Step-by-step explanation:
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
