Answer:
f(3)=3³+2×2²-2-1=27+8-3=32
The answer is B..........
B=160+ 5c
b= 304- 3c
160+5c=304-3c
+3c +3c
160+8c=304
-160 -160
8c= 144
c=18
<span>To find the range of this function, simply plug each of the end values into the original equation. In this case, with x of -2, the function becomes f(x) = 6+1 or 7, and with x of 7, the function becomes f(x) = -21+1 or -20. As such, the range of the function is -21 <= f(x) <= 7.</span>
