Which linear function has a graph that includes all of the points in the table?

egoroff_w [7]

Answer:

B. f(x) = 5x - 7

Step-by-step explanation:

✔️Using the table of values given, find the slope (m) and y-intercept (b) of the line of the graph that represents the table, then write the function in slope-intercept form.

✔️Slope (m) using (0, -7) and (2, 3):

Slope (m) = ∆y/∆x

Slope (m) = (3 -(-7))/(2 - 0)

Slope (m) = 10/2

Slope (m) = 5

✔️ y-intercept (b):

b = -7, because where x = 0, y = -7, which is the point where the y-axis is intercepted by the line of the graph.

✔️Write the linear function in slope-intercept form by substituting m = 5 and b = -7 into f(x) = mx + b

Thus:

f(x) = 5x + (-7)

f(x) = 5x - 7

Therefore, the linear function that has a graph that includes all the points in the table would be f(x) = 5x - 7.

Which statements are true for the functions g(x)=x^2 and h(x)=-x^2? Check all that apply

galina1969 [7]

Answer:

if x=0 then they have same value

1 and 2 options are out

for x=-1

g(-1)=1

h(-1)=-1

3 is true

4th

FALSE

for all values except 0, g(x)>h(x)

correct ones are

g(x) > h(x) for x = -1.

For positive values of x, g(x) > h(x).

For negative values of x, g(x) > h(x).

Determine which function(s) is NOT a linear function. Select all that apply.

VLD [36.1K]

Answer:

x=3

Step-by-step explanation:

By vertical line test, x=3 fails because more than 2 points have the same x value. Functions must pass the vertical line test.
