Answer:
C
Step-by-step explanation:
A "zero" of a function is an input value that makes the function value equal zero. On the graph these input values are -3 and 1; you can see that the function values are zero in both cases. C is correct.
Solve the equation for 1 and 5:
1^2 +4 = 1+4 = 5
5^2 + 4 = 25 +4 = 29
Find the difference:
29 -5 = 24
Find the difference of the X values: 5-1 = 4
Rate of change is the change in Y over the change in X:
The rate of change would be: 24/4 = 6
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
