Answer:

B. 4^\frac{1}{2} + 4^\frac{1}{2}

Step-by-step explanation:

Adding exponents with the same bases follows this rule: a^x+a^y=a^{x+y}.

So before Ned merges the exponents together, Ned did answer choice B.

Also, you can check to see if you get 4 by putting it in the calculator.

H(y)=-3y^2+5<br> p(y)=y^3-7y<br> Find (h-p)(y)
gladu [14]

(h-p))(y) = -y^3-3y^2+7y+5

Step-by-step explanation:

Given

h(y) = -3y^2+5\\p(y) = y^3-7y

We have to find the difference of two functions given

So,

(h-p)(y) = h(y) - p(y)\\= (-3y^2+5)-(y^3-7y)\\=-3y^2+5-y^3+7y\\=-y^3-3y^2+7y+5

Hence,

(h-p))(y) = -y^3-3y^2+7y+5
