Answer:

x = 10

Step-by-step explanation:

To find x-intercept/zero, substitute y = 0.

2x + 4 \times 0 = 20

Any expression multiplied by 0 equals 0.

2x + 0 = 20

When adding or subtracting 0, the quantify does not change.

2x = 20

Divide both side of the equation by 2:

x = 10

Answer:

10

Step-by-step explanation:

x- intercept is where the equation intersect the x-axis. So, at x-axis y = 0

2x + 4*0 = 20

           2x = 20

Divide both sides by 2

2x /2 = 20/2

x = 10

Answer:

12

Step-by-step explanation:

The parallel sides must be the same length.

2x-6 = x+3

2x-x-6-3 = 0

x - 9 = 0

x = 9

x + 3 and 2x - 6 are both 12

The graph of y = f(x) is shown. <br> a) Find f(0) <br> 4- <br> 3. <br> b) Give the roots of f(x) = 0
Amanda [17]

The value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1

<h3>Graph of a function</h3>

From the question, we are to determine the value of f(0) and the roots of f(x) = 0

The value of f(0) is the value of f(x) or the value of y when x = 0

In the given graph, we can observe that the value of y when x = 0 is 2

∴ f(0) = 2

The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0

In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1

∴ The roots of f(x) = 0 are -2 and -1

Hence, the value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1
