Think about the design that worked the best. Could you improve the best design and raise its internal temperature? Think about what materials you could use to improve the design. Here are some things to consider:
• How does the size of the reflective surface affect the temperature of the oven?
. Would insulating the oven help it retain heat, or would more heat be lost?
. Would a tighter or a looser cover heat the oven faster? How about no covering at all?

what design are you talking about?

Explanation:

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.

what exactly is the question lol
