Answer:
f(4) = -15
Step-by-step explanation:
Since we have an average rate of change, we can deduce that a line, with a gradient of -6 joins the points on the function, f, when the parameter is 1 and when it is 4, i.e. the line passes through the point (1, 3) and has a gradient of -6;
From this, we know that for every value of x we increase the, value y will decrease by 6;
So if we increase 1 by 3, to get to 4, the y value must decrease by 18 (3×6);
Written mathematically, it would look like:
f(4) = 3 + (4 - 1)(-6)
= 3 - 18
= -15
(4, -15)
Answer:
No
Step-by-step explanation:
No, because 0.7 is greater than 0.07 {Tip: Look for place of the decimal}
0.7 is written as 7/10 and 0.07 is written as 7/100
0.7 which is 7/10 is also written as 70/100 Hence, it clearly that 70/100 is greater than 7/100
0.7 is greater than 0.07 because to compare between two decimal numbers, you should look at the number after the decimal point and 7 is greater than 0 in the tenth place.

Answer:
-1/3
Step-by-step explanation:
2^2 + 3x - 3 = 0
4 - 3 + 3x = 0
1 + 3x = 0
x = -1/3
