3, if you do the y^2-y^1/x^2-x^1 you will get 3/1 which will be simplified to 3.
Answer:
2x² + 
x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 
- 2 + 2x² + x - 3 ← collect like terms
= 2x² + x - 5
Answer:
2.50
Step-by-step explanation:
The average rate of change over the interval −2≤x≤2 is:
(f(2) − f(-2)) / (2 − -2)
From the table, we see that f(2) = 14 and f(-2) = 4.
(14 − 4) / (2 − -2)
10 / 4
2.50
Answer:
5/8
Step-by-step explanation:
.625 can equal 625/1000
and you can shrink the answer down with simplification.
cause you can divide both numerator and denominator by 5
625/1000 = 125/ 200
And we can divide both sides again by 5.
125/ 200 = 25/ 40
and we can divide both sides again by 5 once again.
25/ 40 = 5/ 8
