Answer:
2x^2-x+1
Step-by-step explanation:
Answer:
2x² - x + 1
Step-by-step explanation:
Answer:
x-axis
Step-by-step explanation:
r=4 cos5θ
∙Subsitute (r,-θ)in the given function
4 cos〖5θ=4 cos5(-θ) 〗,then r(θ)=r(π-θ)
∴Thus,it is symmetric about x-axis.
Since
4 cos〖5θ≠-4 cos5(π-θ) 〗
∴Thus,it is not symmetric about y-axis.
∙Since
4 cos〖5θ≠-4 cos5(π+θ) 〗
∴Thus,it is not symmetric about the origin
