Function with 2 Variables
For each value of y that
is greater than 4√3 the function f(x) is such that the equation f(x) = y has
the form x = (y2+11)/(y−3).
Select one value for a and
one value for b such that the given information implies f(a) = b. Make only two
selections, one in each column.
a |
b |
|
|
|
4 |
|
|
7 |
|
|
15 |
|
|
18 |
|
|
27 |
Appreciate your answers and reasoning.
Thanks,
Stephen
start replacing the options in expression and for each b find the value of a.
since b>4*root(3) ignore option b=4;
for b=7, find a; a=15 (available in option)
other values of b and a combinations not available in options.
The answer is b=7 and a=15
