Answer:

1) f(3) = 1

2) x = -1

Step-by-step explanation:

1) Whenever a question is asking to find or evaluate what f(3) is, it is asking to find the corresponding y-value of the function based on the number in the parentheses, which is given the x-value. Thus, the question is asking, "what is the y-value of the point on the graph that has an x-value of 3?" By reading the graph, we can see that it passes through (3,1), thus 1 is the answer.

2) f(x) is another way of saying y. Thus, the question is asking, "what is the x-value of the point on the graph with a y-value of 3?" By reading the graph, we can see that the line passes through (-1, 3). Thus, the answer would be -1.

sophia is 6 years older than her brother eric. the sum of their ages is 28. write and solve an equation to find sophia and Eric'
zimovet [89]

s = 6 + e

s + e = 28

We can use this system of equations to find the exact values of s and e.

We have a current value of s, so we can find the exact value of e now.

e + e + 6 = 28

<em><u>Combine like terms.</u></em>

2e + 6 = 28

<em><u>Subtract both sides by 6.</u></em>

2e = 22

<em><u>Divide both sides by 2.</u></em>

e = 11

Now we have an exact value of e, and can solve for the value of s.

s = 6 + 11

s = 17

Sophia is 17 years old, and Eric is 11 years old.
