F(X)= 2x^2 +1. Find and simplify af(X)+b and f(ax+b)

kati45 [8]

Hello,

f(x)=2x²+1
f(ax+b)=2(ax+b)²+1=2(a²x²+2abx+b²)+1=2a²x²+4abx+2b²+1

af(x)+b=a(2x²+1)+b=2ax²+a+b

And f(ax+b)≠af(x)+b not linear

Answer:

Let’s find out...

Step-by-step explanation:

21 x 13 = 273

(13 x 20) + (13 x 1) =

260 + 13 = 273

So this one matches

(21 x 10) + 213 =

210 + 213 = 423

Does not match

(30 x 13) - (9 x 13) =

390 - 117 = 273

This one matches

(20 x 10) + (1 x 3) =

200 + 3 = 203

Does not match

A baker has 8 5/8 cups of flour to make cupcakes. The baker used all of his flour to make 3 5/6 dozen cupcakes. How many cups of

frozen [14]

Answer: 1 dozen cupcakes can be made in 12 cups of flour.

Step-by-step explanation:

Given : The amount of flour a baker has = $8\dfrac{5}{8}\text{ cups}= \dfrac{8\times8+5}{8}\text{ cups}$

$=\dfrac{69}{8}\text{ cups}$

The number of cupcakes he made by using all flour = $3\dfrac{5}{6}=\dfrac{6\times3+5}{6}=\dfrac{23}{6}$

i.e. $\dfrac{23}{6}$ cupcakes made in $\dfrac{69}{8}$ cups of flour

By unitary method ,

1 cupcake made in $\dfrac{69}{8}\times\dfrac{6}{23}$ cups of flour.

i.e. 1 cupcake made in $\dfrac{9}{4}$ cups of flour.

Then , 12 cupcakes can be made in $12\times\dfrac{9}{4}$ cups of flour.

= 27 cups of flour.

Since<em> 1 dozen = 12</em>

Then , 1 dozen cupcakes can be made in 12 cups of flour.
