Answer:
The range is [-11, ∞).
Step-by-step explanation:
f(x)=3x^2+6x-8
This is a parabola which opens upwards.
Convert to vertex form:
= 3(x^2 + 2x) - 8
= 3 [ (x + 1)^2 - 1] - 8
= 3(x + 1)^2 - 3 - 8
= 3(x + 1)^2 - 11.
The minimum value is -11 so the range is [-11, ∞).

Answer:
n=16
Step-by-step explanation:
Make an equation
Three times a number minus 9–> 3n-9
Times means multiply, and minus means subtract
Equals two times the number plus 7–> =2n+7
Times means multiply, and plus means add
3n-9=2n+7
Solve for n, by getting n by itself
Subtract 2n from both sides
3n-2n-9=2n-2n+7
n-9=7
Add 9 to both sides
n-9+9=7+9
n=16

9 and 1/3
Division of fractions includes three major steps. Keep the first number, change the division symbol to multiplication, and find the reciprocal of the last number. If you do all these steps correctly (make sure to change the mixed number to an improper fraction), you should get the equation 14/3 x 2/1 = 28/3. 28/3= 9 and 1/3. Thus, the answer is 9 and 1/3.
