$\\ \sf\longmapsto (x^2-2x)^2-8=7(x^2-2x)$

$\\ \sf\longmapsto x^4-4x^3+2x^2-8=7x^2-14x$

$\\ \sf\longmapsto x^4-4x^3-5x^2+14x-8=0$

Answer:

2a + b/4

Step-by-step explanation:

The expression is the sum of two terms (2a + b/4)

The first term is the product (Multiply) of 2 and a (2a)

The second term is the quotient (Divide) of b and 4 (b/4)

f(x) = x2 – 3x – 2 is shifted 4 units right. The result is g(x). What is g(x)?g(x) = (x + 4)2 – 3x – 2 B. g(x) = (x + 4)2 – 3(x

Hello from MrBillDoesMath!

Answer:

Choice C

Discussion:

We interrupt this Question by a special commercial announcement..... Consider the simpler case of f(x) = x^2. If we shifted this curve 4 units to the right, then the point x is mapped to x-4. (f(0) = 0 on the original curve; now f(x-4) = 0 when x =4. So shifting to the right replaces x by x-4.) Now back to our regular TV programming....

Shifting f(x) = x^2 -3x - 2 four units to the right produces

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

This is choice C.

Thank you,

MrB
