Y = f(x) = 2^x

Virty [35]

Answer:

The value of f(x) when x=-1 is 0.5

Therefore $f(-1)=0.5$

Step-by-step explanation:

Given that y=f(x)= $2^x$

to find the f(x) when x=-1 :

That is to find f(-1)

Put x=-1 in the given function f(x)= $2^x$

$f(-1)=2^{-1}$

$=\frac{1}{2}$

$=0.5$

Therefore $f(-1)=0.5$

The value of f(x) when x=-1 is 0.5

Solve the system of linear equations using the

MArishka [77]

Answer:

no solution

Step-by-step explanation:

y = -2x + 3

6x + 3y = -3

the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation

6x + 3(-2x + 3) = -3

6x - 6x + 9 = -3

9 = -3

which is false meaning that there are no solutions and the lines don't touch at any point
