Easy...

to even begin to factor..you must factor out a 3, to simplify your answer.

3(12 $x^(2)$ -7x-10)

Now, you can factor.

$3(12 x^(2) -7x-10)$

So..to find the answer...

12*-10=-120x
and
you would use -7x

What multiplies to -120..but adds to -7?

-15*8=-120
and
-15+8=-7

To find the answer, plug in what you know..

3(3x+2)(4x-5)

Thus, your answer.

Answers

The y intercept occurs when x = 0

So for first function y-intercept = 3.

Second function:-

y intercept = -4 sin (5*0) + 3

= -4(0) + 3 = 3

y - intercepts are equal.
