F(x) = x² + 5x-1 is shifted 3 units right. The result is g(x). What is g(x)?

CaHeK987 [17]

Answer:

Step-by-step explanation:

When a function is being shifted to the left, all x values will be added by y units shifted. (The constant that comes with x is excluded, eg. 3x shifted by 2 units left, becomes 3(x+2) and not 3x+2.)

Likewise, when a function is being shifted to the right, all x values will be subtracted by y units shifted. (Constant rules applies as well.)

Given f(x) is shifted 3 units right,

the new function, g(x) becomes:

$g(x) = {(x - 3)}^{2} + 5(x - 3) - 1$

Therefore the answer is D in this case.

In a group of 25 factory workers, 20 are low-risk and five are high-risk. two of the 25 factory workers are randomly selected wi

Aleks04 [339]

Let
L=event that a selected worker has low risk
H=event that a selected worker has high risk

We need to find
P(HL)+P(LH)
=5*20/(25*24)+20*5/(25*24)
=1/6+1/6
=1/3
