Suppose f(x) = x2 and g(x) = 2x − 3. What is the value of g(4) + f(−3)?

MAVERICK [17]

In order to find the value of g(4)+f(-3), we must substitute those values into the functions first.

Substitute -3 into f(x).

f(x)=x²

f(-3)=(-3)²

f(-3)=9

Substitute 4 into g(x).

g(x)=2x-3

g(4)=2(4)-3

Using the rules of PEMDAS, multiply first then subtract.

g(4)=8-3

g(4)=5

Therefore, if f(-3) is 9 and g(4) is 5, we must add the two values together.

5+9=14

<u>The value of g(4)+f(-3) is 14.</u>

What is the slope of the line through (-9, 6) and (-6, -9)?

yKpoI14uk [10]

The answer is C, you use the equation for slope, m=y-y/ x-x . I used to get really confused by these but what I found easy was writing out the two points and labling them (x1,y1) and (x2,y2). Don’t get confused by the numbers that follow x and y , they aren’t exponents they are just so you know what goes where. Hope this helped
