4x² - 19 → B

substitute x = g(x) into f(x)

f(g(x)) = f(x² - 5) = 4(x² - 5 ) + 1 = 4x² - 20 + 1 = 4x² - 19

The first thing to is factor the denominator of the rational function:
x^{2} -2x-3 to do this we'll need to find two number whose product is -3 and its sum is -2; those numbers are 1 and -3, so:
x^{2} -2x-3=(x+1)(x-3)
Now we can rewrite our rational function as follows:
f(x)= \frac{x-3}{(x+1)(x-3)}
Notice that we have a common factor (x-3) in both numerator and denominator; therefore we can cancel them:
f(x)= \frac{1}{x+1}

Taking all the above into consideration we realize that x=3 is a removable discontinuity; the correct answer is the first one: there is a hole in x=3 and asymptote  at x=-1.

HELP!! Identify the transformation from ABC to A'B'C'.
elena55 [62]

Answer:

<em>Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.</em>

<em>Choice 1.</em>

Step-by-step explanation:

<u>Reflection over the x-axis</u>

Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).

The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.

1. Layne rode his bike from Point A to B by
postnew [5]

Answer:

cherry street is 85 yards, while orange dr. and peach ave. is 113 yards, meaning that cherry st. is 28 yards faster

Step-by-step explanation:

(85 x 85) - (77 - 77) = 1296

square root of 1296 is 36

77 + 36 = 113

113 - 85 = 28

this means that cherry st. is 28 yds faster

using the Pythagorean Theorum
