Consider the graph that represents the following quadratic equation y=-1/3(x+2)^2+5

makkiz [27]

We have that
y=-1/3(x+2)²+5

using a graph tool
see the attached figure

we know that
1) the graph open downward
2) the vertex of the graphic is the point (-2,5)
3) the axis of symmetry of the graph is x=-2
4) the x intercept values are (-5.873,0) and (1.873,0)
5) the y intercept value is (0,3.667)

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.

3/4 + ( 1/3 divided by 1/6 - (-1 /2 a. 3/4 b. 1 3/4 c. 3 1/4 d. 2 1/4

andrew-mc [135]

answer:

A is the answer because you need to divide it and add it together and then u get 3.25 which is also a fraction for 3/4
