Answer:
Find slope first:
Substitute a TWO points into the above slope formula:
Points: (-2, 0) and (0, 1)
Slope is (1 / 2).
Substitute slope into slope point formula:
y - y1 = m (x - x1)
y - y1 = (1 / 2) (x - x1)
Substitute a point in the above equation:
Sub point (0, 1)
y - 1 = (1/2) (x - 0)
y - 1 = 1/2x
Get equation by solving for y:
y = 1/2x + 1
She gives away n books per week, so If
, then she has (
) books left at any time.
this will be the explicit formula.
so we need to write in terms of recrusive.
to be recrusive each term must be expressed in terms of previous term.
in this represent } [/tex] in terms of
replace w+1 in place of w .
.
. this will be the recrusive expression for number of books she left.
We have been given the function
We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.
Now, we simplify this step by step.
First of all . Thus, we have
Now, we can easily simplify it by PEMDAS
Therefore, the value of f(3) is 98.
