Answer:

-3

Step-by-step explanation:

f(-2) = (-2)^2 + 10 = 14 -> (-2, 14)

f(-1) = (-1)^2 + 10 = 11 -> (-1, 11)

(11-14)/(-1-(-2)) = -3/1 = -3

Which of the following equations is the formula of f(x) = x^1/3 but shifted 4 units to the left and 4 units up?
nlexa [21]

Answer:

Hence correct chcie is C.

f\left(x\right)=(x+4)^{\frac{1}{3}}+4

Step-by-step explanation:

Given function is f\left(x\right)=x^{\frac{1}{3}}

Now it says that function is shifted 4 units to the left and 4 units up.

We need to find about which of the given choice is correct for the given transformation.

When f(x) is shifted "h" units left then we write f(x+h)

So f\left(x\right)=x^{\frac{1}{3}} will change to

f\left(x\right)=(x+4)^{\frac{1}{3}}

When f(x) is shifted "h" units up then we write f(x)+h

So f\left(x\right)=(x+4)^{\frac{1}{3}} will change to

f\left(x\right)=(x+4)^{\frac{1}{3}}+4
