  (a)  f(x) = -2|x| + 1

Step-by-step explanation:

Adding a value to a function translates it vertically by that value.

Multiplying a function by a value scales it vertically by that factor. If the factor is negative, a reflection over the x-axis is also involved.

Here, the parent function y=|x| has been reflected over the x-axis, expanded vertically by a factor of 2, and translated upward by 1 unit. This combination of effects is produced by ...

  f(x) = -2|x| +1

You know the vertical scale factor is 2, because the slopes of the lines have a magnitude of 2. A 1-unit change horizontally gives a 2-unit change vertically.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
