A function f is given by the formula f(x)=a⋅ekx for constants a and k. we also know that f(4)=12 and f(7)=5. find numerical valu

masha68 [24]

The given function is

$f(x) = a e^{kx}$

And it is given that $f(4)=12$

On using this information, we will get

$12 = a e^{4k}$

And the other point is $f(7)=5$

Using this point, we will get

$5= ae^{7k}$

Dividing both equations, we will get

$\frac{12}{5} = e^{4k-7k}$

Taking ln to both sides

$ln( \frac{12}{5} ) = -3k$

$k = -0.29$

Performing back substitution ,

$12 = a e^{-0.29*4}
\\
a =38.28$

If g(x) = 1 - ¾ x find: -5g(4) - 1

cricket20 [7]

Answer:

-5g(4) - 1 is 9

Step-by-step explanation:

$g(x) = 1 - \frac{3}{4} x$

when x is 4:

$g(4) = 1 - \frac{3}{4} \times 4 \\ = 1 - 3 \\ = - 2$

therefore:

$- 5g(4) - 1 = - 5( - 2) - 1 \\ = 10 - 1 \\ = 9$
