Horizontal translations
Suppose that h> 0
To graph y = f (x + h), move the graph of h units to the left.
We have then:
g (x + 5) = (x + 5) 2 + 3 (x + 5) - 4
Rewriting we have:
f (x) = x ^ 2 + 10x + 25 + 3x + 15 - 4
f (x) = x ^ 2 + 13x + 36
Equaling zero we have:
x ^ 2 + 13x + 36 = 0
We look for the roots of the polynomial:
(x + 9) (x + 4) = 0
x1 = -9
x2 = -4
Answer:
The zeros of the new function are:
x1 = -9
x2 = -4
Answer:
30 cm.
Step-by-step explanation:
We can solve this problem by making a proportion:
1 cm/65 km = x cm/1,950 km
By cross-multiplying, we can solve for x:
65x = 1,950
x = 30
Answer:
400
Step-by-step explanation:
Answer:
–21.87 ÷ 4.79
≈ -20 ÷ 5
≈ -4
Step-by-step explanation:
front end estimation means to round off to the most left digit.
eg 12 ≈ 10
