Answer:

Step-by-step explanation:

The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;

M(X,Y) = {(x1+x2)/2, (y1+y2)/2}

Given the points A(h, k) and B(h,j)

x1 = h, y1 = k, x2 = h, y2 = j

Substitute into the formula;

M(X,Y) = {(x1+x2)/2, (y1+y2)/2}

M(X,Y) = {(h+h/2, (k+j)/2}

M(X,Y) = {(2h)/2, (k+j)/2}

M(X,Y) = {h, k+j/2}

hence the coordinates of point M is {h, k+j/2}

lisov135 [29]

The function is given f(x)=2^x+3.

Now let's solve for f(-2).

f(-2)=2^{-2}+3

Rule of negative exponent: x^{-1}=\frac{1}{x^1}.

f(-2)=\frac{1}{2^2}+3

f(-2)=\frac{1}{4}+\frac{3}{1}

Rule for sum of fractions: \frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}.

f(-2)=\frac{13}{4}

And the result is:

f(-2)=\boxed{\frac{13}{4}=3.25}
