8 - ? = -1. the missing number would be 9.
"Alaina’s sugar cookie recipe calls for 2 1/4
cups of flour per batch. If she wants to make 2/3
a batch of cookies, how much flour should she use?"
1 1/2 Cups, if she wants to make less than the original recipe, she would need less flour, you have to divide.
Answer:
1 is not a transformation
2 is a reflection
3 is a dilation
4 is a translation
Step-by-step explanation:
Answer:
D. ![f(x)=4x^{2}+1](https://tex.z-dn.net/?f=f%28x%29%3D4x%5E%7B2%7D%2B1)
Step-by-step explanation:
There is a translation 1 point up along the y axis and a compression of 4.
Moving a function up (let's use <em>h</em> for the amount of points up) would change the function as so:
![f(x)=x^{2} +h](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%20%2Bh)
Meanwhile, the compression would modify x in this case. You can eliminate any answers (A. and B.) that have no modification to x, and eliminate C., as a fraction modification would actually widen the graph instead of compress it.
Hope this helps! :]
