Answer:

1.5

Step-by-step explanation:

i am not certain but this is how I got it

First distribute which gives you the -3 with 2 I switched them around so I did -3(-5x+2) and you will get 15x-6

Then the opposite of subtraction is addition so you add 6 to both sides so you add six to 12 and to 6 leaving you with 15x=3x+18 you then will subtract 3x from 15x and 3 leaving you with 12x=18 the divide the numbers

After you divide you get 3/2 then put it has a decimal and you get 1.5

What are the domain and range of the function f(x)=-3(x-5)squared+4
svet-max [94.6K]
Domain is all real numbers
range
hmm
we know that x^2=a positive number
then multiply it by that negative -3
therefor the range is going to be mostly negative
if we make the x-5  equal to zero, then there is no negative, so
wher x=5, then f(5)=0+4=4
the highest positive number you can get is f(5)=4

so therfor

domain=all real number
range is x≤4
