Find the value(s) of x if f(x) = 1.
A. 9
C. -1.5
B. 4
D. both a and c

D. both a and c

Step-by-step explanation:

We want to find the x value when the y value is 1

There are two x values when the y value is 1

When x = -1.5  y=1  and when x = 9  y = 1

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
