B. Reflection over the x axis, dilation with a scale factor of 1/2

When you get a question like this, choose the option that includes “dilation.” Dilation changes the size of the shape while keeping similarity.

If f(x)=(x+3)³+4<br> let g(x)=f(x+1)-2<br> find when g(x)=12

Alla [95]

Answer:

Explanation:

g(x) = f(x + 1) - 2

g(x) = (x + 1 + 3)^3 -2

g(x) = (x + 4)^3 - 2

Now what are we supposed to do with this? I'm guessing we are to find what value of x will make g(x) = 12. If I'm wrong, leave a note in the form of a comment.

g(x) = 12

(x + 4)^3 - 2 = 12 Add 2 to both sides.

(x + 4)^3 = 14 Take the cube root of both sides.

x + 4 = cubrt(14)

x + 4 = 2.4101 Subtract 4

x = 2.4101 - 4

x = -1.5899

Which expression is equivalent to x2 - 12x + 11?

Serjik [45]

Answer: o (x - 11)(x - 1)

Explanation:

You can find two values that has a sum of -12 and a product of 11:

$x^{2} -12x+11\\(x-11)(x-1)$

Or you can use the quadratic formula:

$\frac{-b+-\sqrt{b^{2} -4ac} }{2a}$

Where:

a = 1
b = -12
c = 11
