The average rate of change of a function between x = a to x = b is f(b) - f(a) / (b - a). Now use this formula to find the rate of change of the function f(x) = x^2 between x = 4 to x = 8 *
Choose a
1) 8
2) 4
3) 80/12
4) 12

4) 12

Step-by-step explanation:

f(4) = 4² = 16

f(8) = 8² = 64

(64 - 16)/(8 - 4)

48/4

12

step-by-step explanation:

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
