You plug 11 in where x is.
r(11) = (11 + 1)(11 - 3)
= (12)(8)
= 96
Answer:
31.4
Step-by-step explanation:
So a really easy way to solve this is as goes
--> 3.14 x (20 x 1/2)
--> 3.14 x (10)
Now multipling by 10 is just moving the deciaml place one spot to the right
=> thus, we get 31.4
Hope this helps!
F(2)=1
f(2) means that 2 is being plugged in for x so look for the y value when x is 2
in this case y is 1 when x is 2
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~
To solve this we will first find out what f(x) equals at the given point of 4, and than substitute that answer it for g(f(4))...
f(x) = x - 7
f(4) = 4 - 7 = -3
g(f(4)) = (x - 7)^2 > -3^2 = 9
So...
The answer is: g(f(4)) = 9
