Answer: f(1)=0
Step-by-step explanation:
replace x by 1
f(1)= 1-2(1)+10(1)-18+9
f(1)= 1-2+10-18+9
f(1)= 1+10+9-2-18
f(1)= 20-20
f(1)= 0
Answer:
B)6
Step-by-step explanation:
g = x - 9
Let x = 15
g = 15-9
g = 6
A circle is tangent only when y and x axis collide
81 Because 3•3•3•3= 81 then I added the negative sign. but I guess you should do -3•-3=9 then again -3•-3=9. then 9•9 equals 81.
