Math help please? Giving brainliest and 25 points!!!!!!
algol [13]
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) ]

Which function below is the inverse of f(x)= 3x+5/7
Ipatiy [6.2K]
Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x

so

f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3
\frac{y- \frac{5}{7} }{3}=x
replace with f⁻¹(x)

f⁻¹(x)=\frac{y- \frac{5}{7} }{3}

What does ‘x’ equal
Dmitriy789 [7]

Answer:

x=(-9)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(−2/3)(9+x)=0

(−2/3)(9)+(−2/3)(x)=0(Distribute)

−6+−2/3x=0

−2/3x−6=0

Step 2: Add 6 to both sides.

−2/3x−6+6=0+6

−2/3x=6

Step 3: Multiply both sides by 3/(-2).

(3−2)*(−2/3x)=(3−2)*(6)

x=−9
