Arectangular picture frame measures 4.0 inches by 5.5 inches. to cover
the picture inside the frame with glass costs $0.99 per square inch.
what will be the cost of the glass to cover the picture?

area = 4 x 5.5 = 22 square inches

cost is 0.99 per sq. inch

22 * 0.99 = 21.78

 cost is $21.98

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
