What is this type of math called please and what year/grade if you don’t mind me asking so I can be prepared
2x^2+3. the 2x cancel out and the rest is combining like terms
Answer:
The answer is 2
From the function when the input is 2 the output is -7. The inverse reverses the order so the input will be -7 and the output will be 2.
Answer:

OR

Step-by-step explanation:
Hi there!
Point-slope form:
where <em>m</em> is the slope of the line and
is a given point
Given that the slope is -3/4, we can plug it into
as <em>m</em>:

We can also plug in the given point (1,2):

Slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis)
To write the equation in slope-intercept form, isolate <em>y</em>:

I hope this helps!
