Question

g(x)= -0.5x^2+3x+4 when g(x) =-5. trying to find x-intercepts.

Answer 1

No real values of solutions (x-intercepts)...

Answer 2

Not an option. =\ It's online homework.

Answer 3

-5 = -0.5x^2 +3x + 4
-0.5x^2 +3x + 9 = 0

-x^2 + 6x + 18 = 0

x1,2 = (-6 +/- (36 + 72)^0.5) / -2
x1,2 = 3 +/- (27)^0.5
x1,2 = 3 +/- 3*(3^0.5)

Answer 4

so x=6 or x=0?

Answer 5

no

3 + 3* (3^0.5) = 8.196....
3 - 3 * (3^0.5) = -2.196..

Answer 6

instead of 3 * (3^0.5) you can say 27^0.5
hope it is better for you now

Answer 7

Thank you so much!!
