A = 4. B = 1. The b’s cancel each other out. Then you have 2a = 8. Divide 8 by 2 and get 4. That’s a=4. Then put a back into either problem. So 4+_=5. B=1. 16-1=15. 15 is the answer

Use the graph of f(x) to find the indicated function values.

Julli [10]

Answer:

If x=0 , then f(0)=2
If f(x)=0 , then x = -1

Step-by-step explanation:

First lets assume that the y axis is called the ordinate axis and the x axis is the abscissa axis

Then:

The first question asks for the y value in the ordinate axis that corresponds to the x = 0 value. To begin:

You must start to locate the x=0 value on the abscissa axis, its located in the center of the axis.

Then you start for searching the y value that the curve takes when it passes through the ordinate axis, this correspond to the value of the function f(x) on x=0. The value according to the graph is y=2.

Then , you located the point (0,f(0))=(0,2).

The second question asks for the x value in the abscissa axis that corresponds to the f(x)=y=0 value. To begin this, you start the other way around:

You must locate the y=0 value on the ordinate axis, its also located in the center of the axis.

Then you start for searching the x value that the function needs to take the y=0 value. According to the graph the value of x that the function needs is x = -1

Then, you located the point where f(x)=y=0, its (-1,0).
