Muke is sick with the flu but he still cors to school on monday. He areives at 8am and by 9am (hour 1) muke has already infected

Volgvan

Answer:

$\begin{array}{ccccccccc}{Hours} & {0} & {1} & {2} & {3} & {4}& {5} & {6} & {7} \ \\ {Persons} & {1} & {2} & {4} & {8} & {16}& {32} & {64} & {128} \ \end{array}$

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Complete the table

Let

$x = hours$

$y = persons$

From the table question, we have:

$(x_1,y_1) = (0,1)$

$(x_2,y_2) = (1,2)$

$(x_3,y_3) = (2,4)$

The pattern follows that, an increment in x by doubles the value of 1.

So, the other values are:

$(x_4,y_4) = (3,8)$

$(x_5,y_5) = (4,16)$

$(x_6,y_6) = (5,32)$

$(x_7,y_7) = (6,64)$

$(x_8,y_8) = (7,128)$

So, the complete table is:

$\begin{array}{ccccccccc}{Hours} & {0} & {1} & {2} & {3} & {4}& {5} & {6} & {7} \ \\ {Persons} & {1} & {2} & {4} & {8} & {16}& {32} & {64} & {128} \ \end{array}$

Solving (b): The graph

The table follows an exponential function:

$y = ab^x$

We have: $(x_1,y_1) = (0,1)$

This gives:

$y = ab^x$

$1 = ab^0$

$b^0 \to 1$

So:

$1 = a*1$

$1 = a$

$a =1$

Also: $(x_5,y_5) = (4,16)$

This gives:

$y = ab^x$

$16 = 1 * b^4$

$16 = b^4$

$16 \to 2^4$

So:

$2^4 = b^4$

Cancel the exponents (4)

$2 =b$

$b = 2$

So, the function $y = ab^x$ is:

$y = 2^x$
