The function h is a quadratic function whose graph is a translation 7 units left and 9 units up of the parent function f(x) = x

slamgirl [31]

Answer:D ( if you add +4 to the (x + 3)^2)

Step-by-step explanation:

Parent function is f(x) = x^2

A translation 3 units left gives y = )x + 3)^2

- and 4 up gives y = (x + 3)^2 + 4 - vertex form.

Standard form :

y = x^2 + 6x + 9 + 4

= x^2 + 6x + 13.

Jayne says that 0.45 is equal to 4/10. Is she correct? Explain.

No, 4/10 is equal to 0.40 and not 0.45 since 4/10 goes in tens.
