3=6

In this case, the pattern is the number, in this case, 3, multiplied by the number below it.

See?
8\times7=56\\7\times6=42\\6\times5=30\\5\times4=20\\3\times2=6

Hope this helped :)

100 POINT HELP PLEASE !!!!!!!!!!! NO LINKS
NikAS [45]

y = log(3x + 4) + 2

__________________________________________________________

Y-INTERCEPT: set x = 0

y = log(3(0) + 4) + 2

y = log(0 + 4) + 2

y = log( 4) + 2

Using calculator,

y = log( 4) + 2

y ≈ 2.60 when x = 0

__________________________________________________________

X-INTERCEPT: set y = 0

y = log(3x + 4) + 2

0 = log(3x + 4) + 2

-2 = log(3x + 4)

(it's simple. Always remember that the base is 10, even though there seems to be no "smaller number" next to log)

= 3x + 4

10^{-2} - 4 = 3x

[10^{-2} - 4 ] /3 = x

x = -1.33 when y = 0

__________________________________________________________

<h3>ANSWER: y-intercept is 2.60 and x-intercept is -1.33</h3>
