We can also use the triangle inequality to us find bounds on functions. the triangle inequality tells us that |f(x) + g(x)| ≤ |f(x)| + |g(x)|. a) use the triangle inequality, together with the fact that |ab| = |a| ⋅ |b| to show that |f(x) − g(x)| ≤ |f(x)| + |g(x)|. b) use the triangle inequality to find a bound for f(x) = x 3 − 7x 2 + 3x − 5 on the interval [−2, 1]. be careful to justify all of your steps.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

the aswere is the one with all 8's and the second one is with the 10,8 and 6
