Find f(-4) please help

f(-4)=11

Step-by-step explanation:

f(-4) means you plug in -4 where it can be plugged in. Since you have a piecewise function, find where x can be -4, and you'll see it's the first one because that equation works when x<3, which -4 is smaller than 3

Plug in -4, and that's your answer

f(x)=x^2-5

f(-4)=(-4)^2-5

f(-4)=16-5

11

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
