Answer:
16x² - 8x + 8
Step-by-step explanation:
f(x)=4x-1
g(x)=x²+7
g(f(x)) = g(4x-1) = (4x - 1)² + 7 = 16x² - 2*4x*1 +1² + 7= 16x² - 8x + 8
Answer:
The slope would be the gradient of the line and hence by comparison with the equation form y=mx+c where m is the gradient, the gradient of the line in the question would be 7/4.
The y intercept of the line would be where x=0. When x=0, the y intercept is thus -10.
Hence the answer is the first option
Answer:
642.8
Step-by-step explanation:
1607 divided by 10 = 160.7 x 4 = 642.8
