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

What is the vertex form of the equation Y=-x^2-12x-4 Please show all the steps

denis-greek [22]

Answer:

$\boxed{\bold{y=-(x+6)^2+32}}$

Step-by-step explanation:

$y=-x^2-12x-4\\\\y=-(x^2+12x)-4\\\\y=-(\underline{x^2+2\cdot x\cdot6+6^2}-6^2)-4\\\\y=-\left[(x+6)^2-36\right]-4\\\\y=-(x+6)^2+36-4\\\\\bold{\underline{y=-(x+6)^2+32}}$

If 100% is $50 And 125% is $62.50 What is 135%? Thank you,

shutvik [7]

Answer:

Step-by-step explanation:

So, I subtracted 62.5 minus 50 that equals 12.5

So, then you would do 12.5 times 135% equals 16.87

Then you would add 62.5 and 16.87

Therefore your answer is 75
