Given:
for x=-4 and x=4, find value of f(x) if f(x) is piecewise defined as follows:
f(x)=x² if x≤-4, and ..........(1)
f(x)=sqrt(x) if x>1...............................(2)
f(-4)=x ² =(-4)^2= +4*4=+16 [ from (1) ]
f(4)=sqrt(x) =sqrt(4) = 2 [ from (2) ]
Answer:
a
Step-by-step explanation:
I think it is undefined
Answer:

Step-by-step explanation:
The function is given :
f(x) = 4x + 15
For f(-3), the input for the function f(x) is -3.
Replace the x variable with -3.
f(-3) = 4(-3) + 15
Evaluate.
f(-3) = -12 + 15
f(-3) = 3
The output for f(-3) is 3.
1a) f(4) = 2
1b) x = 1 and x = 3
2a) g(3) = 55
2b) If you work 5 hours... you could expect to earn $85 (according to the function)
Hey there :)
We know the volume formula of a triangular prism
Volume = base area × height of prism
We are given:
Base of triangle = 5 ft
Height of triangle = 3 ft
Height of prism = 7.5 ft
Apply the formula
V =

( 5 )( 3 ) × 7.5
= 7.5 × 7.5
= 56.24 ft³
