Answer:

$f(x)=-\frac{1}{2}(10^x)$

Step-by-step explanation:

Let the exponential function be $f(x)=a(b^x)$ .

When x=0, $f(0)=-\frac{1}{2}$

$-\frac{1}{2}=a(b^0)$

$a=-\frac{1}{2}$

The function now becomes $f(x)=-\frac{1}{2}(b^x)$

When x=1, f(1)=-5

This implies that:

$-5=-\frac{1}{2}(b^1)\\ \implies b=10$

Therefore the equation for the exponential function represented in the table below is $f(x)=-\frac{1}{2}(10^x)$

this is bad but i did that work and i kept getting 10.6 and 10.8 is the closest so...

cos (45) = x/15 *put cos (45) over 1 & cross multiply*

x = 15 (cos (45))

x = 10.6
