Step-by-step explanation:

We have to find the fractions of whole numbers.

Number 1:

$\frac{1}{5}$ of 10 = $\frac{1}{5} \times (2 \times 5) = 2$ (Answer)

Number 2:

$\frac{2}{3}$ of 9 = $\frac{2}{3} \times (3 \times 3) = 2 \times 3 = 6$ (Answer)

Number 3:

$\frac{7}{8}$ of 32 = $\frac{7}{8} \times (4 \times 8) = 7 \times 4 = 28$ (Answer)

Number 4:

$3 \times 10^{2} + 5 \times 10^{1} + 8 \times 10^{0} + 1 \times \frac{1}{10^{2} }$

= $3 \times 100 + 5 \times 10 + 8 \times 1 + \frac{1}{100}$ {Since $a^{0} = 1$ }

= 300 + 50 + 8 + 0.01

= 358.01 (Answer)

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
