PLEASE HELP I RLLY DONT KNOW WHAT TO DO
Jlenok [28]

Answer:

a) f(0) = -9

b) f(2) = -5

c) f(-3) = -15

d) f(1/2)=-8

Step-by-step explanation:

We are given the function f(x)=2x-9 and we need to find the following:

a) f(0)

For finding f(0) put x =0 in the given function

f(x)=2x-9\\Put\:x=0\\f(0)=2(0)-9\\f(0)=-9

So, we get f(0)=-9

b) f(2)

For finding f(2) put x =2 in the given function

f(x)=2x-9\\Put\:x=2\\f(2)=2(2)-9\\f(2)=4-9\\f(2)=-5

So, we get f(2)=-5

c) f(-3)

For finding f(-3) put x =-3 in the given function

f(x)=2x-9\\Put\:x=-3\\f(-3)=2(-3)-9\\f(-3)=-6-9\\f(-3)=-15

So, we get f(-3)=-15

d) f(1/2)

For finding f(1/2) put x =1/2 in the given function

f(x)=2x-9\\Put\:x=\frac{1}{2}\\f(\frac{1}{2})=2(\frac{1}{2})-9\\f(\frac{1}{2})=1-9\\f(\frac{1}{2})=-8

So, we get f(1/2)=-8

Need help fast on a timer
nikitadnepr [17]

Answer:

D,  10i\sqrt{2}

Step-by-step explanation:

Separate -1, 2, and 100 from each other inside the radical. You can take out -1 as <em>i</em>, and 100 as 10. You now have 10<em>i</em> on the outside of the radical and 2 on the inside. Hope this helps.
