Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
Take note that they spent $18 afterwards having $28 on the card so they're spending money off the card so...
x-18=28
would be the equation for this and to solve do the following.
First add 18 to both sides making the equation.
x=46
The equation would be 8x +3 + -19. Substitute your given answers in. Your answer would be B. Negative 2

Answer:
6 14/15
Step-by-step explanation:
I would say simplifie the paratensies.
First:
3 2/3+ 17 1/5 =
Common factor of 3 and 5 is 15
3 10/15 + 17 3/15 = 20 13/15
Second:
11 3/5 + 2 1/3 =
Common factor of 3 and 5 is 15
11 9/15 + 2 5/15 = 13 14/15
20 13/15 - 13 14/15 = 7 13/15 - 14/15 = 7 - 1/15 = 6 14/15
