Just put 0 first and the multiply 0 by 2x and then add 1 and do that with every single number like 1. 1x2 = 2+1 = 3

Sometimes, especially after a little experience, you can tell from the "form" of the equation what the "shape" of the graph is. If you can tell the shape then it makes plotting the graph easier, but for the moment let's just try to plot it without knowing the shape beforehand. To do this I am going to use a table of values. I am going to choose some values for the variable x, calculate the corresponding value of y and then record my results in a table. So, for example when x = 1 then y = 2 <span> 1 + 1 = 3 and when x = 2 then y = y = 2 </span><span> 2 + 1 = 5</span>

Which statement is true regarding the graphed functions? A) f(4)=g(4) B) f(4)=g(-2) C) f(2)=g(-2) D) f(-2)=g(-2)

Answer:

Option (D)

Step-by-step explanation:

If the two points $(x_1,y_1)$ and $(x_2,y_2)$ are lying of the line.

Slope of the line represented by the function 'f' = $\frac{y_2-y_1}{x_2-x_1}$

Two points are lying on the line are (-2, 4) and (0, -2).

Slope of the line passing through these points 'm' = $\frac{4+2}{-2-0}$

m = -3

Y-intercept of the line 'b' = -2 [From the graph]

Therefore, equation of the function will be,

f(x) = (-3)x - 2

f(x) = -3x - 2

Similarly, for other function represented by the line in red,

Slope of the line passing through (-6, 0) and (0, 6) = $\frac{6-0}{0+6}$

m' = 1

Y-intercept of g(x) = 5 [From the graph]

Equation that represents the function g(x) = 1.x + 5

g(x) = x + 5

For g(x) = f(x)

-3x - 2 = x + 6

-3x - x = 2 + 6

-4x = 8

x = -2

Therefore, for x = -2 both the functions will have the value.

f(-2) = g(-2)

Option (D) will be the answer.

sergij07 [2.7K]

She earned 661.50 dollars. If she worked 7.5 hrs each day Mon-Wed, she worked 22.5 hrs from Mon-Wed because 7.5 times 3 is 22.5. She also worked 6 hrs on Sat. and 5.25 hrs on Sun., so in total, she worked 33.75 hrs last week. To find out her pay, we have to multiply the total hrs by the amount she gets payed, 19.60. 33.75x19.60 is 661.50, the amount she got payed last week.
