the first x < 3 so x could be from - 1 till 3 in this graph
the other x > - 7 so x could be from from - 7 till - 3 in this graph
Answer:
1/3
Step-by-step explanation:
Simplify 4-3 = 1 and 4-1 =3 so itd be 1/3

Answer:
(2)
Step-by-step explanation:
Our logarithmic expression is: 
.
Remember the logarithmic property that ln(a/b) = lna - lnb. So, we can write this as:
Also, we can write square roots as powers of one-half, so √e = 
. There's another log property that: 
. We can apply that here for both the √e and the y³:
Finally, note that ln(e) is just 1, so we have:
The answer is thus (2).

Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y
Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0
Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0 (this is intercept form)
Solution 1
4x + 1 = 0
4x = -1
x = -1/4
Solution 2
x - 5 = 0
x = 5
SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
