1. Find f(x) if it is known that f(x+5)=x+12.

uranmaximum [27]

Answer:

1. f(x)=x+7

2. f(x)=1.2x

Step-by-step explanation:

1. If f(x+5)=x+12, then substitute

$t=x+5\Rightarrow x=t-5$

Hence,

$f(t)=(t-5)+12\\ \\f(t)=t+7$

Now change t into x:

$f(x)=x+7$

2. If f(x-5)=1.2x-6, then substitute

$t=x-5\Rightarrow x=t+5$

Hence,

$f(t)=1.2(t+5)-6\\ \\f(t)=1.2t+6-6\\ \\f(t)=1.2t$

Now change t into x:

$f(x)=1.2x$

Find the formula for the nth term of the arithmetic sequence -7, -4, -1 , 2

jok3333 [9.3K]

Answer:

Step-by-step explanation:

(-4)-(-7) = -4 + 7 = 3

(-1)-(-4) = 3

2-(-1) = 3

then the common difference r = 3

and the first term is -7

since the nth term = first term + (n - 1)×r

then the nth term = -7 + (n - 1)×3

= -7 + 3(n - 1)
