I can’t figure out what it is asking. How do you find where each line crosses the y-axis?..
EleoNora [17]
They want you to find the y intercept. This is the point where the curve or line crosses the y axis. To find the y intercept, plug in x = 0

y = 3x+4
y = 3*x + 4
y = 3*0 + 4 ... notice x has been replaced with 0
y = 0 + 4
y = 4

So when x = 0, the value of y is y = 4. This means the y intercept is located at the point (0,4). This is all for problem 1. Problem 2 is handled much the same way.

Simplify using PEMDAS <br><br>18-(3x5)+(2B-3B)​
KonstantinChe [14]
First, you need to multiply 3x5 and Sunday you 2B-3B. Now the problem is 18-15+-1. Since there is no exponents, multiplication, or division in this problem anymore, we are going to add. 15+-1=0. Now we have 18-0. 18-0=18. Therefore the answer is 18

Given f(x)= 2^x and g(x)=x+1, (f*g)(x)
kati45 [8]

Answer:

x2ˣ + 2ˣ

Step-by-step explanation:

<u>Points to remember</u>

(f * g)(x) = f(x) * g(x)

It is given that,  f(x)= 2ˣ and g(x)=x+1

<u>To find the value of (f * g)(x) </u>

Let  f(x)= 2ˣ and g(x) = x + 1

(f * g)(x) = f(x) * g(x)

 =  (2ˣ )* (x + 1)

 = (2ˣ * x) + ( 2ˣ * 1)

  = x2ˣ + 2ˣ
