Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
I think the answer will be C
Line graphs can be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.
X • 1.5 = 300
So...
300/ 1.5 = 200
