Answer:
7.) 7
10.) 0
Step-by-step explanation:
When it means "evaluate the function", it's in essence asking us to see what the function spits out when we feed it a certain input. Our inputs are our x values, which spit out a y value.
Evaluating the function when x = 1:
Let's look at where the function has an x value of 1. We see it near the bottom of the table and see the y value associated with the input is 7. So when the function is fed 1 as an input, it spits out 7.
Evaluating the function when f(x) = - 2:
This one is a weird because of the new notation. Just think of it as some value of f, which we don't know (so we represent it as an x-variable) must equal -2. So let's look at our table to find out where our output is -2. We find that when f(x) = -2 the input is 0. So the input which gives -2 is 0.
Answer:
The last option.
Step-by-step explanation:
When you multiply a negative by a negative it makes a positive number. Therefore, if you multiply an even number of negative numbers, you get a positive product. The other options have an odd number of negative numbers to multiply by that makes them result in a negative product.
Answer:
the vertex is 4
Step-by-step explanation:
It would be 6 because the other short side is 6 so it should be 6 units
M=(y2-y1)/(x2-x1) <em>(Multiplied terms on both sides of equation by (x2-x1).)</em>
m(x2-x1)=y2-y1 <em>(Added y1 to both sides of equation, ultimately isolating y2.)</em>
y2=m(x2-x1)+y1
