Answer:
Step-by-step explanation:
Given function is,
f(x) = -8x² + 4
Step to find the inverse of the function,
Step 1
Write the function in the form of an equation,
y = -8x² + 4
Step 2
Interchange the variables 'x' and 'y',
x = -8y² + 4
Step 3
Solve the equation for y,
x = -8y² + 4
x - 4 = -8y²
-x + 4 = 8y²
y² =
Therefore, inverse of the function f(x) will be,
Answer:
(-1, -9)
Step-by-step explanation:
Recall that for 2 points (x1, y1) and (x2,y2)
the midpoints are given by
x ordinate =
y ordinate =
In our case x1 = 8, y1 = -10, x2 = -10, y2=-8
x ordinate = = [8 + (-10) ] / 2 = -1
y ordinate = = [-10 + (-8) ] / 2 = -9
hence midpoint is (-1, -9)
