Which equation represents a function of x that is not linear? y = 4(x + 3) В y = 4? + 3x C y = 4x + 3x² %| 4 + x y = 3 3 4. Triangle A and triangle B are graphed on the coordinate plane below. 8 7 6 4 A 3 2 1 -8 -7 -6 -5 -4 -3 -2 -1 1 2 3 4 6 7 8 -1 -2 -3 -4 -5 -6 -7 -8 Which sequence of transformations will map triangle A onto its congruent image, triangle B? A a reflection over the x-axis, then a reflection over the y-axis В a translation 8 units down, then a reflection over the y-axis a reflection over the x-axis, then a translation 6 units to the left D a rotation 90° clockwise about the origin, then a translation 6 units to the left

Which graph represents a linear function of x ? A →x D →x 1 2. At a factory, the cost of making different numbers of toothbrushes is shown in the table below. COST OF TOOTHBRUSHES Number of 3 6 12 Toothbrushes Cost (dollars) $4.50 $9.00 $13.50 $18.00 A linear function models the cost based on the number of toothbrushes made. Which statement about the rate of change of this function is true? A The cost increases by $1.50 for each additional toothbrush made. В The cost increases by $4.50 for each additional toothbrush made. The cost increases by $9.00 for each additional 3 toothbrushes made. The cost increases by $18.00 for each additional 3 toothbrushes made.
