Question

True or false16. The y-intercept of the equation, = −7^2 + 11 − 12 is 12

Answer 1

For us to be able to determine if it is true or false, let's evaluate the given equation:

`\text{ y = -7x}^2\text{ + 11x - 12}`

In order to find the y-intercept of a function, we substitute x equals to 0. A y-intercept always has an x-coordinate of 0.

Thus, we get,

`\text{ y = -7x}^2\text{ + 11x - 12}`
`\text{ y = -7(0)}^2\text{ + 11(0) - 12}`
`\text{ y = -7(0)}^{}\text{ + 0 - 12 = 0 + 0 - 12}`
`\text{ y = -12}`

The y-intercept of the given equation is -12.

Therefore, the answer is FALSE.
