It helps if you have an example, like f(x) = 2x+3
What you typically do, is:
- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved.
- The more points you calculate, the more accurate your graph will be
Answer:
b = -4/3
Step-by-step explanation:
First, subtract the 1/2 over
-1/4b+1/2=5/6
5/6-1/2
To get a common denominator of 6, multipy 1/2 by 3
5/6-1/2(3)
5/6-3/6=2/6
-1/4b=2/6
Next, multiply by the reciprocal of -1/4, or -4
(-4)-1/4b=2/6(-4)
b=-4/3

Answer:
96feet
Step-by-step explanation:
Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2
x is the number of feet away from the sprinkler head the spray
To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;
From the equation
ℎ(x)=160−16x^2
h(2) = 160-16(2)²
h(2) = 160-16(4)
h(2) = 160-64
h(2) = 96feet
Hence the height will be 96feet if the spray is 2feet away from the sprinklers head
